This book was released on 2020 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: It performed deep inelastic scattering off tritium and helium-3 mirror nuclei to measure F2n/F2p over the range x = 0.17 to x = 0.82. Since tritium and helium-3 are mirror nuclei, theoretical uncertainties largely cancel out in the ratio. The extracted F2n/F2p has much smaller uncertainties compared with previous experiments at large x. The MARATHON experiment also provided results on the EMC effect for tritium and helium-3 nuclei. The results are considered essential for understanding the EMC effect. This thesis describes the MARATHON experiment, and presents results for F2n/F2p, and the EMC effect for tritium and helium-3.

Book excerpt: Proton structure functions are measured in electron-proton collision through inelastic scattering of virtual photons with virtuality Q on protons; x denotes the momentum fraction carried by the struck parton. Proton structure functions are currently described with excellent accuracy in terms of scale dependent parton distribution functions, defined in terms of collinear factorization and DGLAP evolution in Q. With decreasing x however, parton densities increase and are ultimately expected to saturate. In this regime DGLAP evolution will finally break down and non-linear evolution equations w.r.t x are expected to take over. In the first part of the talk we present recent result on an implementation of physical DGLAP evolution. Unlike the conventional description in terms of parton distribution functions, the former describes directly the Q dependence of the measured structure functions. It is therefore physical insensitive to factorization scheme and scale ambiguities. It therefore provides a more stringent test of DGLAP evolution and eases the manifestation of (non-linear) small x effects. It however requires a precise measurement of both structure functions F2 and FL, which will be only possible at future facilities, such as an Electron Ion Collider. In the second part we present a recent analysis of the small x region of the combined HERA data on the structure function F2. We demonstrate that (linear) next-to-leading order BFKL evolution describes the effective Pomeron intercept, determined from the combined HERA data, once a resummation of collinear enhanced terms is included and the renormalization scale is fixed using the BLM optimal scale setting procedure. We also provide a detailed description of the Q and x dependence of the full structure functions F2 in the small x region, as measured at HERA. As a result, predictions for the structure function FL are found to be in agreement with the existing HERA data.

Book Synopsis Experimental Study of Initial State Radiative Events at HERA and a Measurement of the Proton Longitudinal Structure Function by : Jason Schwartz
Download or read book Experimental Study of Initial State Radiative Events at HERA and a Measurement of the Proton Longitudinal Structure Function written by Jason Schwartz and published by . This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A first measurement of the radiative contribution to deep inelastic electron-proton scattering has been performed with the ZEUS detector at HERA. Results show consistency with predictions made by the HERACLES Monte Carlo program. New calibration and simulation of the far luminosity measurement system, including a photon calorimeter and two aerogel Cherenkov detectors, have been implemented. Both calibration and simulation were applied to tag photons produced in the initial state radiative process. These tagged events were used to perform measurements of the deep inelastic ep scattering reduced cross section down to momentum transfer squared, Q2 = 3.0 GeV2, a region normally inaccessible to ZEUS. A determination of the radiative contribution to deep inelastic scattering has aided in the measurement of the structure functions F2 and FL, which were simultaneously extracted in the kinematic region 8.0 GeV2
Book Synopsis Measurement of the Proton and Deuteron Spin Structure Functions G1 and G2 by :

Available in PDF, EPUB and Kindle. Book excerpt: The SLAC experiment E155 was a deep-inelastic scattering experiment that scattered polarized electrons off polarized proton and deuteron targets in the effort to measure precisely the proton and deuteron spin structure functions. The nucleon structure functions g1 and g2 are important quantities that help test our present models of nucleon structure. Such information can help quantify the constituent contributions to the nucleon spin. The structure functions g1{sup p} and G1{sup d} have been measured over the kinematic range 0.01 ≤ x ≤ 0.9 and 1 ≤ Q2 ≤ 40 GeV2 by scattering 48.4 GeV longitudinally polarized electrons off longitudinally polarized protons and deuterons. In addition, the structure functions g2{sup p} and g2{sup d} have been measured over the kinematic range 0.01 ≤ x ≤ 0.7 and 1 ≤ Q2 ≤ 17 GeV2 by scattering 38.8 GeV longitudinally polarized electrons off transversely polarized protons and deuterons. The measurements of g1 confirm the Bjorken sum rule and find the net quark polarization to be [Delta][Sigma] = 0.23 ± 0.04 ± 0.6 while g2 is found to be consistent with the g2{sup WW} model.
Book Synopsis Proton Structure by : William L. Stubbs
Download or read book Proton Structure written by William L. Stubbs and published by CreateSpace. This book was released on 2015-03-12 with total page 106 pages. Available in PDF, EPUB and Kindle. Book excerpt: Beta decay implies that electrons and positrons reside within the nucleus of the atom. However, despite countless observations of electrons and positrons leaving the nucleus, the discovery of the neutron put an end to that notion. Proton Structure examines data collected on the proton over 50 years, to determine what a proton looks like. The book discusses the techniques used to interpret the data, in a manner many can understand. It walks, step-by-step, through the data collected, explaining what each aspect of the data reveals, to make a strong case for protons (and neutrons) made of electrons and positrons. Finally, it briefly looks at some implications of having nucleons made of these particles. Proton Structure takes another look at the structural data gathered on the proton, and offers a model of the proton that fits nicely into the world we see around us.

Book Synopsis Measurement of F2n /F2p from Deep Inelastic Electron Scattering Off A by : Tong Su
Download or read book Measurement of F2n /F2p from Deep Inelastic Electron Scattering Off A written by Tong Su and published by . This book was released on 2020 with total page 154 pages. Available in PDF, EPUB and Kindle. Book excerpt: This research is part of the Jefferson Lab MARATHON experiment (MeAsurement of the F2n /F2p , d/u RAtios and A = 3 EMC Effect in Deep Inelastic Electron Scattering Off the Helium MirrOr Nuclei). MARATHON is an experiment on electron deep inelastic scattering off the 3H, 3He mirror nuclei. It has extracted, from the measured deep inelastic scattering cross section ratio off 3H and 3He, the ratio of the neutron to proton inelastic structure functions F2n /F2p. The extraction has taken advantage of the isospin symmetry of the A = 3 mirror nuclei within a novel technique, which avoids the theoretical uncertainties that are present in the SLAC experiments of the 1970s, which used hydrogen and deuterium targets. The experiment was performed using the upgraded 11 GeV beam of the Jefferson Lab electron accelerator, the Hall A Experimental Facility, and a newly designed cryogenic, high-pressure gas target system containing 3H and 3He cells. Electrons scattered off the gas targets were detected in the two superconducting, high-resolution magnetic spectrometers of Hall A. The cross section data cover the four-momentum transfer squared range 2.0

Book Synopsis Deep Inelastic Scattering by : Robin Devenish
Download or read book Deep Inelastic Scattering written by Robin Devenish and published by OUP Oxford. This book was released on 2011-04-28 with total page 418 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides an up-to-date, self-contained account of deep inelastic scattering in high-energy physics, intended for graduate students and physicists new to the subject. It covers the classic results which led to the quark-parton model of hadrons and the establishment of quantum chromodynamics as the theory of the strong nuclear force, in addition to new vistas in the subject opened up by the electron-proton collider HERA. The extraction of parton momentum distribution functions, a key input for physics at hadron colliders such as the Tevatron at Fermi Lab and the Large Hadron Collider at CERN, is described in detail. The challenges of the HERA data at 'low x' are described and possible explanations in terms of gluon dynamics and other models outlined. Other chapters cover: jet production at large momentum transfer and the determination of the strong coupling constant, electroweak interactions at very high momentum transfers, the extension of deep inelastic techniques to include hadronic probes, a summary of fully polarised inelastic scattering and the spin structure of the nucleon, and finally a brief account of methods in searching for signals 'beyond the standard model'.
Book Synopsis Probing Hadrons with Leptons by : G. Preparata
Download or read book Probing Hadrons with Leptons written by G. Preparata and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 506 pages. Available in PDF, EPUB and Kindle. Book excerpt: Physicists actively engaged in advanced research should be en couraged to discuss results and deepen their theoretical understand ing of the data. It is practically impossible nowadays to achieve the goal of the old times when small groups of scientists had the privilege of debating their ideas and the details of their experi ments in an informal and friendly way. Conferences are now too wide in scientific coverage and, in consequence, there are often too many participants. The Highly Specialized Seminars of the Ettore Majorana Centre for Scientific Culture are intended to provide such a forum for scientists of outstanding reputation in their fields to exchange information. This volume deals with one of the most interesting topics in subnuclear physics, and Professor Giuliano Preparata is one of the world's leaders in the field. This volume contains the most recent results on the study of deep inelastic phenomena, using neutrinos, muons and electrons against nucleons, and (e+e- ) interactions. It represents our best knowledge of the field as given by some of the most distinguished world experts in the theoretical and experimental domain. Antonino Zichichi, Director Ettore Majorana Centre for Scientific Culture v PREFACE In March 1979, about 50 physicists gathered in Erice to parti cipate in the Fourth Highly Specialized Seminar on "Probing Hadrons with Leptons."
