laboratories and national institutes to provide input to the process in various forms and at various stages:</p> <ol> <li>Submission of main input from the community by 31 March 2025 (guidelines available <a href="/sites/default/files/Guidelines-input-call-March_2025.pdf">here</a>)</li> <li>Additional input from the national HEP communities in advance of the Open Symposium (deadline 26 May 2025)</li> <li>Participation in the Open Symposium that will take place from 23 – 27 June 2025</li> <li>Based on the input collected (March and May 2025, and at the Open Symposium) and on the summaries in the Physics Briefing Book  (publication end September 2025), further input from the national HEP communities is welcome ahead of the December 2025 Strategy drafting session (deadline 14 November 2025).</li> </ol> <p>A major component of the community input are the “national inputs”, which are expected to be collected individually by each country (and in some cases by regions). The information collected from the different countries/regions will be most useful if it is as coherent and as uniform as possible when addressing the key issues. To assist with this, the European Committee for Future Accelerators (ECFA) has put together a <a href="https://ecfa.web.cern.ch/ecfa-guidelines-collecting-input-european-high-energy-physics-community-2026-update-european">set of guidelines</a> for the collection of inputs from the national HEP communities.</p> <p><span style="font-size:12.0pt"><span style="line-height:107%"><span style="font-family:"Aptos",sans-serif"><span style="font-size:11.0pt"><span style="line-height:107%"><span style="font-family:"Aptos",sans-serif">It is anticipated that a number of proposals for large-scale research projects (capital investment of at least 250 MCHF) – including, but not limited to, particle colliders and collider detectors – will be submitted as input to the strategy process. These proposals are likely to vary in scale, anticipated timeline, and technical maturity.</span></span></span></span></span></span></p> <p>In order to allow for proper comparison of the physics potential of the various projects, the Physics Preparatory Group (PPG) has defined <a href="/sites/default/files/Benchmark_measurements_processes.pdf">benchmark measurements and processes</a>. It is expected that corresponding results will be included in the project's submissions. </p> <p><span style="font-size:12.0pt"><span style="line-height:107%"><span style="font-family:"Aptos",sans-serif"><span style="font-size:11.0pt"><span style="line-height:107%"><span style="font-family:"Aptos",sans-serif">In addition to studying the scientific potential of these projects, the ESG wishes to evaluate the sequence of delivery steps and the challenges associated with delivery, and to understand how each project could fit into the wider roadmap for European particle physics. In order to allow a straightforward comparison of projects, we therefore request that all large-scale projects submit – in addition to their physics case and technical description – a <a href="/sites/default/files/Large-Scale%20Projects_%20Guidelines%20for%20Input.pdf">standardised set of technical data</a>.</span></span></span></span></span></span></p> <p>All inputs shall be submitted via this <a href="https://indico.cern.ch/event/1439855/">portal</a>.
