Book excerpt: We provide an assessment of the impact of parton distributions on the determination of LHC processes, and of the accuracy with which parton distributions (PDFs) can be extracted from data, in particular from current and forthcoming HERA experiments. 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{sub 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.

Download or read book The CJ12 Parton Distributions written by and published by . This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Three new sets of next-to-leading order parton distribution functions (PDFs) are presented, determined by global fits to a wide variety of data for hard scattering processes. The analysis includes target mass and higher twist corrections needed for the description of deep-inelastic scattering data at large x and low Q2̂, and nuclear corrections for deuterium targets. The PDF sets correspond to three different models for the nuclear effects, and provide a more realistic uncertainty range for the d quark PDF compared with previous fits. Applications to weak boson production at colliders are also discussed.

Download or read book A Global Analysis of Recent Experimental Results written by and published by . This book was released on 1990 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: Following is a brief summary of the results of an analysis of experimental data performed to extract the patron distribution functions. In contrast to other global analyses, this study investigated how the fit results depend on: Experimental Systematic Errors; Kinematic Cuts on the Analyzed Data and Choice of Initial Functional Forms, with a prime goal being a close look at the range of low-x behavior allowed by data. This is crucial for predictions for the SSC/LHC, HERA, and even at Tevatron Collider energies. Since all details can be found in the just released Fermilab preprint Parton Distributions from a Global QCD Analysis of Deep Inelastic Scattering and Lepton-Pair Production by J.G.M. and Wu-Ki Tung, this summary will be only a brief outline of major results. 11 refs., 13 figs.

Download or read book Quantum Chromodynamics written by Günther Dissertori and published by Oxford University Press. This book was released on 2003-02-06 with total page 560 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides an introduction to Quantum Chromodynamics (QCD), the theory of strong interactions. It covers in full detail both the theoretical foundations and the experimental tests of the theory. Although the experimental chapters focus on recent measurements, the subject is placed into historical perspective by also summarizing the steps which led to the formulation of QCD. Measurements are discussed as they were performed by the LEP experiments at CERN, or at hadron-hadron and lepton-hadron colliders such as the TEVATRON at Fermilab and HERA at DESY. Emphasis is placed on high energy tests of QCD, such as measurements of the strong coupling constant, investigations of the non-abelian structure of the underlying gauge group, determinations of nucleon structure functions, and studies of the non-perturbative hadronization process. This excellent text gives a detailed overview of how QCD developed in the 20th century and where we stand with respect to a quantitative understanding after the turn of the millenium. The text is intended for graduate and postgraduate students as well as researchers, and includes numerous problems and solutions.
Download or read book Small X Behavior of Deep Inelastic Structure Functions in QCD written by A. Ali and published by Elsevier. This book was released on 2016-06-03 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: Small-x Behavior of Deep Inelastic Structure Functions in QCD covers the proceedings of the DESY topical meeting entitled ""Small-x Behavior of Deep Inelastic Structure Functions in QCD"", held in DESY, Hamburg, Germany on May 14-16, 1990. The book focuses on Quantum Chromo Dynamics (QCD) structure function technology, including structure function measurements, photon structure, multi-parton interactions, and hadronic collisions. The selection first offers information on structure function measurements at Hera and pomeron and odderon in QCD and a two-dimensional conformal field theory. Topics include nucleon structure function measurements, handles on the gluon distribution, and photon structure. The book also examines Regge poles in asymptotic free theories; QCD phenomenology of parton distribution functions at small x; and possible parametrization of parton distributions. The text elaborates on low x structure function and saturation of the parton density and photon diffractive dissociation in deep inelastic scattering. The publication also considers multi-parton interactions in high energy hadronic collisions and bound-state quark and gluon contributions to structure functions in QCD. Discussions focus on bound valence-quark distributions, intrinsic gluon distribution of protons, and intrinsic charm-quark distributions. The selection is a dependable reference for readers interested in small-x behavior of deep inelastic structure functions in QCD.

This book was released on 2020-05-29 with total page 344 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book contains proceedings of the 7-week INT program dedicated to the physics of the Electron-Ion Collider (EIC), the world's first polarized electron-nucleon (ep) and electron-nucleus (eA) collider to be constructed in the United States. The 2015 NSAC Long Range Plan recommended EIC as the 'highest priority for new facility construction following the completion of FRIB'. The primary goal of the EIC is to establish precise multi-dimensional imaging of quarks and gluons inside nucleons and nuclei. This includes (i) understanding the spatial and momentum space structure of the nucleon through the studies of TMDs (transverse-momentum-dependent parton distributions), GPD (generalized parton distributions) and the Wigner distribution; (ii) determining the partonic origin of the nucleon spin; (iii) exploring the new quantum chromodynamics (QCD) frontier of ultra-strong gluon fields, with the potential to seal the discovery of a new form of dense gluon matter predicted to exist in all nuclei and nucleons at small Bjorken x — the parton saturation.The program brought together both theorists and experimentalists from Jefferson Lab (JLab), Brookhaven National Laboratory (BNL) along with the national and international nuclear physics communities to assess and advance the EIC physics.

This book was released on 2008-01-15 with total page 366 pages. Available in PDF, EPUB and Kindle. Book excerpt: NuInt07, the fifth in a series of international workshops, was held at Fermi National Accelerator Laboratory in Batavia, IL. It was the successful continuation of a series of workshops focused solely on the understanding and measurement of low energy neutrino-nucleus interactions. Neutrino cross sections in the few-GeV energy range are an important ingredient for neutrino oscillation experiments as well as being interesting in their own right. Such measurements and their accompanying theoretical calculations had not been updated for decades. The goal of this workshop series has been to remedy this situation by providing an environment where both experimentalists and theorists in nuclear and high energy physics can come together to review and discuss recent progress in neutrino-nucleus measurements and calculations.
