The Muon Collider Study (MuC) covers the accelerator complex, detectors and physics for a future muon collider. In 2023, European Commission support was obtained for a design study of a muon collider (MuCol) [3]. This project started on 1st March 2023, with work-packages aligned with the overall muon collider studies. In preparation of and during the 2021-22 U.S. Snowmass process, the muon collider project parameters, technical studies and physics performance studies were performed and presented in great detail. Recently, the P5 panel [4] in the U.S. recommended a muon collider R&D, proposed to join the IMCC and envisages that the U.S. should prepare to host a muon collider, calling this their "muon shot". In the past, the U.S. Muon Accelerator Programme (MAP) [5] has been instrumental in studies of concepts and technologies for a muon collider. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2407.12450v1-abstract-full').style.display = 'none'; document.getElementById('2407.12450v1-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 17 July, 2024; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> July 2024. </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Comments:</span> <span class="has-text-grey-dark mathjax">This document summarises the International Muon Collider Collaboration (IMCC) progress and status of the Muon Collider R&D programme</span> </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2303.08533">arXiv:2303.08533</a> <span> [<a href="https://arxiv.org/pdf/2303.08533">pdf</a>, <a href="https://arxiv.org/format/2303.08533">other</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="Accelerator Physics">physics.acc-ph</span> <span class="tag is-small is-grey tooltip is-tooltip-top" data-tooltip="High Energy Physics - Experiment">hep-ex</span> <span class="tag is-small is-grey tooltip is-tooltip-top" data-tooltip="High Energy Physics - Phenomenology">hep-ph</span> </div> </div> <p class="title is-5 mathjax"> Towards a Muon Collider </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/physics?searchtype=author&query=Accettura%2C+C">Carlotta Accettura</a>, <a href="/search/physics?searchtype=author&query=Adams%2C+D">Dean Adams</a>, <a href="/search/physics?searchtype=author&query=Agarwal%2C+R">Rohit Agarwal</a>, <a href="/search/physics?searchtype=author&query=Ahdida%2C+C">Claudia Ahdida</a>, <a href="/search/physics?searchtype=author&query=Aim%C3%A8%2C+C">Chiara Aim猫</a>, <a href="/search/physics?searchtype=author&query=Amapane%2C+N">Nicola Amapane</a>, <a href="/search/physics?searchtype=author&query=Amorim%2C+D">David Amorim</a>, <a href="/search/physics?searchtype=author&query=Andreetto%2C+P">Paolo Andreetto</a>, <a href="/search/physics?searchtype=author&query=Anulli%2C+F">Fabio Anulli</a>, <a href="/search/physics?searchtype=author&query=Appleby%2C+R">Robert Appleby</a>, <a href="/search/physics?searchtype=author&query=Apresyan%2C+A">Artur Apresyan</a>, <a href="/search/physics?searchtype=author&query=Apyan%2C+A">Aram Apyan</a>, <a href="/search/physics?searchtype=author&query=Arsenyev%2C+S">Sergey Arsenyev</a>, <a href="/search/physics?searchtype=author&query=Asadi%2C+P">Pouya Asadi</a>, <a href="/search/physics?searchtype=author&query=Mahmoud%2C+M+A">Mohammed Attia Mahmoud</a>, <a href="/search/physics?searchtype=author&query=Azatov%2C+A">Aleksandr Azatov</a>, <a href="/search/physics?searchtype=author&query=Back%2C+J">John Back</a>, <a href="/search/physics?searchtype=author&query=Balconi%2C+L">Lorenzo Balconi</a>, <a href="/search/physics?searchtype=author&query=Bandiera%2C+L">Laura Bandiera</a>, <a href="/search/physics?searchtype=author&query=Barlow%2C+R">Roger Barlow</a>, <a href="/search/physics?searchtype=author&query=Bartosik%2C+N">Nazar Bartosik</a>, <a href="/search/physics?searchtype=author&query=Barzi%2C+E">Emanuela Barzi</a>, <a href="/search/physics?searchtype=author&query=Batsch%2C+F">Fabian Batsch</a>, <a href="/search/physics?searchtype=author&query=Bauce%2C+M">Matteo Bauce</a>, <a href="/search/physics?searchtype=author&query=Berg%2C+J+S">J.

The muon collider design aims to deliver physics reach at the highest energies with costs, power consumption and on a time scale that may prove favorable relative to other proposed facilities. In this context, a new international collaboration has formed to further extend the design concepts and performance studies of such a machine. This effort is focused on delivering the elements of a $\sim$10 TeV center of mass (CM) energy design to explore the physics energy frontier. The path to such a machine may pass through lower energy options. Currently a 3 TeV CM stage is considered. Other energy stages could also be explored, e.g. an s-channel Higgs Factory operating at 125 GeV CM. We describe the status of the R&D and design effort towards such a machine and lay out a plan to bring these concepts to maturity as a tool for the high energy physics community. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2203.08033v1-abstract-full').style.display = 'none'; document.getElementById('2203.08033v1-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 15 March, 2022; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> March 2022. </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Comments:</span> <span class="has-text-grey-dark mathjax">23 pages, 3 figures. arXiv admin note: text overlap with arXiv:2201.07895</span> </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2203.07224">arXiv:2203.07224</a> <span> [<a href="https://arxiv.org/pdf/2203.07224">pdf</a>, <a href="https://arxiv.org/format/2203.07224">other</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="Instrumentation and Detectors">physics.ins-det</span> <span class="tag is-small is-grey tooltip is-tooltip-top" data-tooltip="High Energy Physics - Experiment">hep-ex</span> </div> </div> <p class="title is-5 mathjax"> Promising Technologies and R&D Directions for the Future Muon Collider Detectors </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/physics?searchtype=author&query=Jindariani%2C+S">Sergo Jindariani</a>, <a href="/search/physics?searchtype=author&query=Meloni%2C+F">Federico Meloni</a>, <a href="/search/physics?searchtype=author&query=Pastrone%2C+N">Nadia Pastrone</a>, <a href="/search/physics?searchtype=author&query=Aim%C3%A8%2C+C">Chiara Aim猫</a>, <a href="/search/physics?searchtype=author&query=Bartosik%2C+N">Nazar Bartosik</a>, <a href="/search/physics?searchtype=author&query=Barzi%2C+E">Emanuela Barzi</a>, <a href="/search/physics?searchtype=author&query=Bertolin%2C+A">Alessandro Bertolin</a>, <a href="/search/physics?searchtype=author&query=Braghieri%2C+A">Alessandro Braghieri</a>, <a href="/search/physics?searchtype=author&query=Buonincontri%2C+L">Laura Buonincontri</a>, <a href="/search/physics?searchtype=author&query=Calzaferri%2C+S">Simone Calzaferri</a>, <a href="/search/physics?searchtype=author&query=Casarsa%2C+M">Massimo Casarsa</a>, <a href="/search/physics?searchtype=author&query=Catanesi%2C+M+G">Maria Gabriella Catanesi</a>, <a href="/search/physics?searchtype=author&query=Cerri%2C+A">Alessandro Cerri</a>, <a href="/search/physics?searchtype=author&query=Chachamis%2C+G">Grigorios Chachamis</a>, <a href="/search/physics?searchtype=author&query=Colaleo%2C+A">Anna Colaleo</a>, <a href="/search/physics?searchtype=author&query=Curatolo%2C+C">Camilla Curatolo</a>, <a href="/search/physics?searchtype=author&query=Da+Molin%2C+G">Giacomo Da Molin</a>, <a href="/search/physics?searchtype=author&query=Delahaye%2C+J">Jean-Pierre Delahaye</a>, <a href="/search/physics?searchtype=author&query=Di+Micco%2C+B">Biagio Di Micco</a>, <a href="/search/physics?searchtype=author&query=Dorigo%2C+T">Tommaso Dorigo</a>, <a href="/search/physics?searchtype=author&query=Errico%2C+F">Filippo Errico</a>, <a href="/search/physics?searchtype=author&query=Fiorina%2C+D">Davide Fiorina</a>, <a href="/search/physics?searchtype=author&query=Gianelle%2C+A">Alessio Gianelle</a>, <a href="/search/physics?searchtype=author&query=Giraldin%2C+C">Carlo Giraldin</a>, <a href="/search/physics?searchtype=author&query=Hauptman%2C+J">John Hauptman</a> , et al.

However, on the experimental side, such great physics potential is accompanied by unprecedented technological challenges, due to the fact that muons are unstable particles. Their decay products interact with the machine elements and produce an intense flux of background particles that eventually reach the detector and may degrade its performance. In this paper, we present technologies that have a potential to match the challenging specifications of a muon collider detector and outline a path forward for the future R&D efforts. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2203.07224v1-abstract-full').style.display = 'none'; document.getElementById('2203.07224v1-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 14 March, 2022; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> March 2022. </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Comments:</span> <span class="has-text-grey-dark mathjax">Contribution to Snowmass 2021, 27 pages, 15 figures</span> </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2105.12624">arXiv:2105.12624</a> <span> [<a href="https://arxiv.org/pdf/2105.12624">pdf</a>, <a href="https://arxiv.org/format/2105.12624">other</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="Instrumentation and Detectors">physics.ins-det</span> </div> <div class="is-inline-block" style="margin-left: 0.5rem"> <div class="tags has-addons"> <span class="tag is-dark is-size-7">doi</span> <span class="tag is-light is-size-7"><a class="" href="https://doi.org/10.1016/j.nima.2021.166129">10.1016/j.nima.2021.166129 <i class="fa fa-external-link" aria-hidden="true"></i></a></span> </div> </div> </div> <p class="title is-5 mathjax"> Muon detection in electron-positron annihilation for muon collider studies </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/physics?searchtype=author&query=Amapane%2C+N">N.

The idea of a muon collider is very appealing since it would allow to study particle collisions at up to tens of TeV energy, while offering a cleaner experimental environment with respect to hadronic colliders. One key element in the muon collider design is the low-emittance muon production. Recently,the Low EMittance Muon Accelerator (LEMMA) collaboration has explored the muon pair production close to its kinematic threshold by annihilating 45 GeV positrons with electrons in a low Z material target. In this configuration, muons are emerging from the target with a naturally low-emittance. In this paper we describe the performance of a system, to study this production mechanism, that consists in several segmented absorbers with alternating active layers composed of fast Cherenkov detectors together with a muon identification technique based on this detector. Passive layers were made of tungsten. We collected data corresponding to muon and electron beams produced at the H2 line in the North Area of the European Organization for Nuclear Research (CERN) in September 2018. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2105.12624v4-abstract-full').style.display = 'none'; document.getElementById('2105.12624v4-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 31 October, 2021; <span class="has-text-black-bis has-text-weight-semibold">v1</span> submitted 26 May, 2021; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> May 2021. </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2010.16251">arXiv:2010.16251</a> <span> [<a href="https://arxiv.org/pdf/2010.16251">pdf</a>, <a href="https://arxiv.org/format/2010.16251">other</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="Instrumentation and Detectors">physics.ins-det</span> <span class="tag is-small is-grey tooltip is-tooltip-top" data-tooltip="Nuclear Experiment">nucl-ex</span> </div> </div> <p class="title is-5 mathjax"> The FragmentatiOn Of Target Experiment (FOOT) and its DAQ system </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/physics?searchtype=author&query=Biondi%2C+S">Silvia Biondi</a>, <a href="/search/physics?searchtype=author&query=Alexandrov%2C+A">Andrey Alexandrov</a>, <a href="/search/physics?searchtype=author&query=Alpat%2C+B">Behcet Alpat</a>, <a href="/search/physics?searchtype=author&query=Ambrosi%2C+G">Giovanni Ambrosi</a>, <a href="/search/physics?searchtype=author&query=Argir%C3%B2%2C+S">Stefano Argir貌</a>, <a href="/search/physics?searchtype=author&query=Diaz%2C+R+A">Rau Arteche Diaz</a>, <a href="/search/physics?searchtype=author&query=Bartosik%2C+N">Nazarm Bartosik</a>, <a href="/search/physics?searchtype=author&query=Battistoni%2C+G">Giuseppe Battistoni</a>, <a href="/search/physics?searchtype=author&query=Belcari%2C+N">Nicola Belcari</a>, <a href="/search/physics?searchtype=author&query=Bellinzona%2C+E">Elettra Bellinzona</a>, <a href="/search/physics?searchtype=author&query=Bisogni%2C+M+G">Maria Giuseppina Bisogni</a>, <a href="/search/physics?searchtype=author&query=Bruni%2C+G">Graziano Bruni</a>, <a href="/search/physics?searchtype=author&query=Carra%2C+P">Pietro Carra</a>, <a href="/search/physics?searchtype=author&query=Cerello%2C+P">Piergiorgio Cerello</a>, <a href="/search/physics?searchtype=author&query=Ciarrocchi%2C+E">Esther Ciarrocchi</a>, <a href="/search/physics?searchtype=author&query=Clozza%2C+A">Alberto Clozza</a>, <a href="/search/physics?searchtype=author&query=Colombi%2C+S">Sofia Colombi</a>, <a href="/search/physics?searchtype=author&query=De+Lellis%2C+G">Giovanni De Lellis</a>, <a href="/search/physics?searchtype=author&query=Del+Guerra%2C+A">Alberto Del Guerra</a>, <a href="/search/physics?searchtype=author&query=De+Simoni%2C+M">Micol De Simoni</a>, <a href="/search/physics?searchtype=author&query=Di+Crescenzo%2C+A">Antonia Di Crescenzo</a>, <a href="/search/physics?searchtype=author&query=Di+Ruzza%2C+B">Benedetto Di Ruzza</a>, <a href="/search/physics?searchtype=author&query=Donetti%2C+M">Marco Donetti</a>, <a href="/search/physics?searchtype=author&query=Dong%2C+Y">Yunsheng Dong</a>, <a href="/search/physics?searchtype=author&query=Durante%2C+M">Marco Durante</a> , et al.

The main reason is the important role the nuclear fragmentation process plays in both fields, where the health risks caused by radiation are very similar and mainly attributable to the fragmentation process. The FOOT experiment has been developed in such a way that the experimental setup is easily movable and fits the space limitations of the experimental and treatment rooms available in hadrontherapy treatment centers, where most of the data takings are carried out. The Trigger and Data Acquisition system needs to follow the same criteria and it should work in different laboratories and in different conditions. It has been designed to acquire the largest sample size with high accuracy in a controlled and online-monitored environment. The data collected are processed in real-time for quality assessment and are available to the DAQ crew and detector experts during data taking. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2010.16251v1-abstract-full').style.display = 'none'; document.getElementById('2010.16251v1-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 29 October, 2020; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> October 2020. </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/1909.13716">arXiv:1909.13716</a> <span> [<a href="https://arxiv.org/pdf/1909.13716">pdf</a>, <a href="https://arxiv.org/format/1909.13716">other</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="High Energy Physics - Experiment">hep-ex</span> <span class="tag is-small is-grey tooltip is-tooltip-top" data-tooltip="Instrumentation and Detectors">physics.ins-det</span> </div> <div class="is-inline-block" style="margin-left: 0.5rem"> <div class="tags has-addons"> <span class="tag is-dark is-size-7">doi</span> <span class="tag is-light is-size-7"><a class="" href="https://doi.org/10.1088/1748-0221/15/01/P01036">10.1088/1748-0221/15/01/P01036 <i class="fa fa-external-link" aria-hidden="true"></i></a></span> </div> </div> </div> <p class="title is-5 mathjax"> Study of muon pair production from positron annihilation at threshold energy </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/physics?searchtype=author&query=Amapane%2C+N">N.

The LEMMA project is investigating the possibility of producing low emittance muon/antimuon pairs from the e$^+$e$^-$ annihilation process at threshold energy, resulting in small transverse emittance beams without any additional beam cooling. However most of the measurements available are performed at higher $\sqrt{s}$ values. It is therefore necessary to measure muons production in positron annihilation at threshold energy and compare the experimental results with the predictions in this specific energy regime. Apart from being a topic of physical interest by itself, these near to threshold measurements can have a sizeable impact on the estimation of the ultimate luminosity achievable in a muon collider with the LEMMA injection scheme. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('1909.13716v2-abstract-full').style.display = 'none'; document.getElementById('1909.13716v2-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 10 January, 2020; <span class="has-text-black-bis has-text-weight-semibold">v1</span> submitted 30 September, 2019; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> September 2019. </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Comments:</span> <span class="has-text-grey-dark mathjax">13 pages, 8 figures</span> </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Journal ref:</span> 2020 JINST 15 P01036 </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/1905.05747">arXiv:1905.05747</a> <span> [<a href="https://arxiv.org/pdf/1905.05747">pdf</a>, <a href="https://arxiv.org/format/1905.05747">other</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="Accelerator Physics">physics.acc-ph</span> <span class="tag is-small is-grey tooltip is-tooltip-top" data-tooltip="High Energy Physics - Experiment">hep-ex</span> </div> </div> <p class="title is-5 mathjax"> Positron driven muon source for a muon collider </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/physics?searchtype=author&query=Alesini%2C+D">D.

In this paper a layout of a positron driven muon source known as the Low EMittance Muon Accelerator (LEMMA) concept is presented. The positron beam, stored in a ring with high energy acceptance and low emittance, is extracted and driven to a multi-target system, to produce muon pairs at threshold. This solution alleviates the issues related to the power deposited and the integrated Peak Energy Density Deposition (PEDD) on the targets. Muons produced in the multi-target system will then be accumulated before acceleration and injection in the collider. A multi-target line lattice has been designed to cope with the focusing of both the positron and muon beams. Studies on the number, material and thickness of the targets have been carried out. A general layout of the overall scheme and a description is presented, as well as plans for future R&D. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('1905.05747v2-abstract-full').style.display = 'none'; document.getElementById('1905.05747v2-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 19 May, 2019; <span class="has-text-black-bis has-text-weight-semibold">v1</span> submitted 14 May, 2019; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> May 2019. </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Comments:</span> <span class="has-text-grey-dark mathjax">18 pages, 32 figures</span> </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/1903.11534">arXiv:1903.11534</a> <span> [<a href="https://arxiv.org/pdf/1903.11534">pdf</a>, <a href="https://arxiv.org/format/1903.11534">other</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="Instrumentation and Detectors">physics.ins-det</span> <span class="tag is-small is-grey tooltip is-tooltip-top" data-tooltip="High Energy Physics - Experiment">hep-ex</span> </div> <div class="is-inline-block" style="margin-left: 0.5rem"> <div class="tags has-addons"> <span class="tag is-dark is-size-7">doi</span> <span class="tag is-light is-size-7"><a class="" href="https://doi.org/10.1088/1748-0221/14/06/T06006">10.1088/1748-0221/14/06/T06006 <i class="fa fa-external-link" aria-hidden="true"></i></a></span> </div> </div> </div> <p class="title is-5 mathjax"> Cerium-Doped Fused-Silica Fibers as Wavelength Shifters </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/physics?searchtype=author&query=Akchurin%2C+N">N.

Pulsed red laser light with a wavelength of 672 nm is used to generate electron-hole pairs in the sensors. The induced signals are used to determine the charge collection efficiencies separately for electrons and holes drifting through the sensor. The effective trapping rates are extracted by comparing the results to simulation. The electric field is simulated using Synopsys device simulation assuming two effective defects. The generation and drift of charge carriers are simulated in an independent simulation based on PixelAV. The effective trapping rates are determined from the measured charge collection efficiencies and the simulated and measured time-resolved current pulses are compared. The effective trapping rates determined for both electrons and holes are about 50% smaller than those obtained using standard extrapolations of studies at low fluences and suggests an improved tracker performance over initial expectations. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('1505.01824v1-abstract-full').style.display = 'none';
