This book was released on 2002 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent measurements from the HERMES and SMC collaborations show a remarkably large azimuthal single-spin asymmetries AUL and AUT of the proton in semi-inclusive pion leptoproduction[gamma]*(q)p[yields][pi]X. We show that final-state interactions from gluon exchange between the outgoing quark and the target spectator system lead to single-spin asymmetries in deep inelastic lepton-proton scattering at leading twist in perturbative QCD; i.e., the rescattering corrections are not power-law suppressed at large photon virtuality Q[sup 2] at fixed x[sub bj]. The existence of such single-spin asymmetries requires a phase difference between two amplitudes coupling the proton target with J[sub P][sup z]=[+-] 1/2 to the same final-state, the same amplitudes which are necessary to produce a nonzero proton anomalous magnetic moment. We show that the exchange of gauge particles between the outgoing quark and the proton spectators produces a Coulomb-like complex phase which depends on the angular momentum L[sup z] of the proton's constituents and is thus distinct for different proton spin amplitudes. The single-spin asymmetry which arises from such final-state interactions does not factorize into a product of distribution function and fragmentation function, and it is not related to the transversity distribution[delta]q(x, Q) which correlates transversely polarized quarks with the spin of the transversely polarized target nucleon.

Book Synopsis Spin Structure Of The Nucleon - Proceedings Of The The Riken Symposium by : Toshi-aki Shibata
Download or read book Spin Structure Of The Nucleon - Proceedings Of The The Riken Symposium written by Toshi-aki Shibata and published by World Scientific. This book was released on 1996-08-30 with total page 134 pages. Available in PDF, EPUB and Kindle. Book excerpt: After about three decades of experimental and theoretical efforts, the structure of the nucleon (proton and neutron) is now fairly well understood based on quantum chromodynamics, but only if averaged over its spin. As the recent “proton spin crisis” revealed, we do not understand much about the nucleon structure when its spin is polarized to a specific orientation. We expect that our understanding on this challenging problem will soon be significantly improved by the RHIC-Spin and other experiments in the near future, as well as by the lattice- and perturbative-QCD theoretical calculations. The purpose of this symposium was to summarize the current understanding and discuss the future perspective of this problem with experimental and theoretical physicists from both high-energy and nuclear physics communities.The symposium covered the overview of the structure studies, updates on the experimental results from CERN, SLAC, DESY, FNAL, and KEK, future experiments at RHIC, and recent theoretical developments (18 presentations, 113 participants).
Book Synopsis Experimental Results on Polarized Structure Functions in Deep Inelastic Lepton-nucleon Scattering by :
Download or read book Experimental Results on Polarized Structure Functions in Deep Inelastic Lepton-nucleon Scattering written by and published by . This book was released on 1994 with total page 6 pages. Available in PDF, EPUB and Kindle. Book excerpt: A summary is given of experimental results on spin structure functions of the proton g1{sup p}(x, Q2), deuteron g1{sup d}(x, Q2), and neutron g1(superscript n)(x, Q2) as measured in deep inelastic scattering of polarized leptons from a polarized target. All results are consistent with the Bjorken sum rule predictions at the Q2 of each experiment. The data do not support the Ellis-Jaffe sum rule prediction for the proton which implies that the hencity carried by the strange quark may be nonzero and that the net quark helicity is smaller than expected from simple quark models.

Book Synopsis M.a.b. Beg Memorial Volume by : Ali A
Download or read book M.a.b. Beg Memorial Volume written by Ali A and published by #N/A. This book was released on 1991-10-16 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: The M.A.B. BÉG MEMORIAL VOLUME is based on scientific articles written in honor of the late Mirza Abdul Baqi Bég, a professor of physics at the Rockefeller University, New York. The contributed articles are partly based on talks given at the school on high energy physics and cosmology, held March 11 - 25, 1990 at the Quaid-i-Azam University, Islamabad, Pakistan, and partly on articles contributed by his colleagues and collaborators.Being a scientific tribute to Bég, the articles reflect the specific areas of his scientific research and the contemporary trends and open questions in elementary particle physics. Deciphering the mechanism of symmetry breaking with the help of known properties of elementary particles - their masses and couplings — and devising new experimental tests to find clues to the actual physical phenomena at work, are the recurring themes in this book. The role of higher symmetries, formulated in terms of the string and grand unified theories, likewise is elucidated in several articles.The book also contains one of the last articles authored by Bég, written in honor of Luigi Radicati, describing a scientific history of the crucial development from the quark model to the standard model which took place in the sixties.

Book Synopsis Deep Inelastic Scattering (Dis 2001), Procs Of The 9th Intl Workshop by : Graziano Bruni
Download or read book Deep Inelastic Scattering (Dis 2001), Procs Of The 9th Intl Workshop written by Graziano Bruni and published by World Scientific. This book was released on 2002-10-18 with total page 882 pages. Available in PDF, EPUB and Kindle. Book excerpt: The proceedings of DIS 2001 present the most updated status of deep inelastic scattering (DIS) physics. Topics like structure function measurements and phenomenology, QCD studies in DIS and photoproduction, spin physics and diffractive interactions are reviewed in detail, with emphasis on those studies that push the test of QCD and the Standard Model to the limits of their present range of validity, towards both the very high and the very low four-momentum transfers in the lepton-proton scattering. Moreover, this workshop coincided with the transition between the first period of experimentation at the HERA ep collider at DESY and the start of the updated HERA II operation — allowing a review of what has been learned up to now and a discussion on the main future directions of research in this field.

Download or read book Radiative Corrections to Polarized Inelastic Scattering in Coincidence written by and published by . This book was released on 2001 with total page 5 pages. Available in PDF, EPUB and Kindle. Book excerpt: The complete analysis of the model-independent leading radiative corrections to cross-section and polarization observables in semi-inclusive deep-inelastic electron-nucleus scattering with detection of a proton and scattered electron in coincidence has been performed. The basis of the calculations consists of the Drell-Yan like representation in electrodynamics for both spin-independent and spin-dependent parts of the cross-section in terms of the electron structure functions. The applications to the polarization transfer effect from longitudinally polarized electron beam to detected proton as well as to scattering by the polarized target are considered.

Download or read book Impact of Hadronic and Nuclear Corrections on Global Analysis of Spin-dependent Parton Distributions written by and published by . This book was released on 2014 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: We present the first results of a new global next-to-leading order analysis of spin-dependent parton distribution functions from the most recent world data on inclusive polarized deep-inelastic scattering, focusing in particular on the large-x and low-Q2̂ regions. By directly fitting polarization asymmetries we eliminate biases introduced by using polarized structure function data extracted under nonuniform assumptions for the unpolarized structure functions. For analysis of the large-x data we implement nuclear smearing corrections for deuterium and 3He nuclei, and systematically include target mass and higher twist corrections to the g_1 and g_2 structure functions at low Q2̂. We also explore the effects of Q2̂ and W2̂ cuts in the data sets, and the potential impact of future data on the behavior of the spin-dependent parton distributions at large x.
