In the analysis we determined the QCD--scale $螞_{\rm QCD, N_f = 4}^{\bar{\rm MS}} = 265 \pm 27 \MeV {\rm (NLO)}, 226 \pm 25 \MeV {\rm (NNLO)}, 234 \pm 26 \MeV {\rm (N^3LO)}$, with a remainder uncertainty of $\pm 2\MeV$ for the yet unknown 4--loop anomalous dimension, corresponding to $伪_s(M_Z^2) = 0.1148 \pm 0.0019 {\rm NLO}, 0.1134 {\tiny{\begin{array}{c} +0.0019 -0.0021 \end{array}}} {\rm NNLO}, 0.1141 {\tiny{\begin{array}{c} +0.0020 -0.0022 \end{array}}} {\rm N^3LO}$. A comparison is performed to other determinations of the QCD scale and $伪_s(M_Z^2)$ in deeply inelastic scattering. The higher twist contributions of $F_2^p(x,Q^2)$ and $F_2^d(x,Q^2)$ are extracted in the large $x$ region, subtracting the twist--2 contributions obtained in the NLO, NNLO and N$^3$LO analysis. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('hep-ph/0607200v1-abstract-full').style.display = 'none'; document.getElementById('hep-ph/0607200v1-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> 18 July, 2006; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> July 2006. </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">35 pages, 15 figure, 1 style file</span> </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Report number:</span> DESY 05-012, SFB-CPP-06/33 </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Journal ref:</span> Nucl.Phys.B774:182-207,2007 </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/hep-ph/0606309">arXiv:hep-ph/0606309</a> <span> [<a href="https://arxiv.org/pdf/hep-ph/0606309">pdf</a>, <a href="https://arxiv.org/ps/hep-ph/0606309">ps</a>, <a href="https://arxiv.org/format/hep-ph/0606309">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 - Phenomenology">hep-ph</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/10.1142/9789812706706_0028">10.1142/9789812706706_0028 <i class="fa fa-external-link" aria-hidden="true"></i></a></span> </div> </div> </div> <p class="title is-5 mathjax"> NNLO analysis of unpolarized DIS structure functions </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/hep-ph?searchtype=author&query=Bl%C3%BCmlein%2C+J">J.

HERA has been a machine of excellence for the study of QCD and the structure of the proton. The Large Hadron Collider (LHC), which will collide protons with a centre-of-mass energy of 14 TeV, will be completed at CERN in 2007. The main mission of the LHC is to discover and study the mechanisms of electroweak symmetry breaking, possibly via the discovery of the Higgs particle, and search for new physics in the TeV energy scale, such as supersymmetry or extra dimensions. Besides these goals, the LHC will also make a substantial number of precision measurements and will offer a new regime to study the strong force via perturbative QCD processes and diffraction. For the full LHC physics programme a good understanding of QCD phenomena and the structure function of the proton is essential. Therefore, in March 2004, a one-year-long workshop started to study the implications of HERA on LHC physics. This included proposing new measurements to be made at HERA, extracting the maximum information from the available data, and developing/improving the theoretical and experimental tools.

We give an overview of reference LHC processes and their associated PDF uncertainties, and study in detail W and Z production at the LHC. We discuss the precision which may be obtained from the analysis of existing HERA data, tests of consistency of HERA data from different experiments, and the combination of these data. We determine further improvements on PDFs which may be obtained from future HERA data (including measurements of $F_L$), and from combining present and future HERA data with present and future hadron collider data. We review the current status of knowledge of higher (NNLO) QCD corrections to perturbative evolution and deep-inelastic scattering, and provide reference results for their impact on parton evolution, and we briefly examine non-perturbative models for parton distributions. We discuss the state-of-the art in global parton fits, we assess the impact on them of various kinds of data and of theoretical corrections, by providing benchmarks of Alekhin and MRST parton distributions and a CTEQ analysis of parton fit stability, and we briefly presents proposals for alternative approaches to parton fitting. We summarize the status of large and small x resummation, by providing estimates of the impact of large x resummation on parton fits, and a comparison of different approaches to small x resummation, for which we also discuss numerical techniques. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('hep-ph/0511119v1-abstract-full').style.display = 'none'; document.getElementById('hep-ph/0511119v1-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> 9 November, 2005; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> November 2005. </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">Report of Working Group I for the HERA-LHC Workshop</span> </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Report number:</span> IFUM-853-FT </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/hep-ph/0407089">arXiv:hep-ph/0407089</a> <span> [<a href="https://arxiv.org/pdf/hep-ph/0407089">pdf</a>, <a href="https://arxiv.org/ps/hep-ph/0407089">ps</a>, <a href="https://arxiv.org/format/hep-ph/0407089">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 - Phenomenology">hep-ph</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/10.1016/j.nuclphysbps.2004.09.059">10.1016/j.nuclphysbps.2004.09.059 <i class="fa fa-external-link" aria-hidden="true"></i></a></span> </div> </div> </div> <p class="title is-5 mathjax"> Non-Singlet QCD Analysis of the Structure Function F_2 in 3-Loops </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/hep-ph?searchtype=author&query=Bl%C3%BCmlein%2C+J">J.

New parameterizations are derived for the quark and gluon distributions for the kinematic range $x 蔚[10^{-9},1], Q^2 蔚[1,10^6] \GeV^2$. The extrapolation far outside the domain of the current measurements is given both to allow for applications at higher values of $Q^2$ and to be able to calculate integral properties of the present distributions. The values of $螞_{\rm QCD}$ and $伪_s(M_z)$ are determined. Emphasis is put on the derivation of the fully correlated $1蟽$ error bands for these distributions, which are also given in terms of parameterizations and are directly applicable to determine experimental errors of other polarized observables. The impact of the variation of both the renormalization and factorization scales on the value of $伪_s$ is studied. Finally we perform a factorization--scheme invariant QCD analysis based on the observables $g_1(x,Q^2)$ and $d g_1(x,Q^2)/d \log(Q^2)$ in next-to-leading order, which is compared to the standard analysis. A series of low moments of parton densities, accounting for error correlation, are given to allow for comparison with results from lattice simulations. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('hep-ph/0203155v3-abstract-full').style.display = 'none'; document.getElementById('hep-ph/0203155v3-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> 24 May, 2002; <span class="has-text-black-bis has-text-weight-semibold">v1</span> submitted 17 March, 2002; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> March 2002. </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">43 pages LATEX, 1 style files, 13 eps-figures, final version, Nucl.

Finally a factorization-scheme invariant QCD analysis based on the observables $g_1(x,Q^2)$ and $d g_1(x,Q^2)/d \log(Q^2)$ is performed in next-to-leading order, which is compared to the standard analysis. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('hep-ph/0107317v1-abstract-full').style.display = 'none'; document.getElementById('hep-ph/0107317v1-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 July, 2001; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> July 2001. </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">6 pages LATEX, 4 aps style and other files, 3 eps-files, to appear in the Proceedings of `QCD at Work', Martina Franca, June 2001</span> </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Report number:</span> DESY 01-107 </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Journal ref:</span> AIP Conf.Proc. 602 (2001) 94-99 </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/hep-ph/9906408">arXiv:hep-ph/9906408</a> <span> [<a href="https://arxiv.org/pdf/hep-ph/9906408">pdf</a>, <a href="https://arxiv.org/ps/hep-ph/9906408">ps</a>, <a href="https://arxiv.org/format/hep-ph/9906408">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 - Phenomenology">hep-ph</span> </div> </div> <p class="title is-5 mathjax"> RADGEN 1.0.
