A Collection of Polarized Parton Densities
نویسنده
چکیده
A significant number of parameterizations for the polarized parton densities have appeared in the literature. Using the CTEQ evolution package, these distributions have been evolved consistently preparatory to compilation into an integrated package in the spirit of PDFLIB by Plothow-Besch. Here, a comparison of a few of the more recent distributions are made. Table 1: This is a partial listing of parameterizations for the polarized parton distribution functions. ∆PDFs ∆PDFs AUTHORS REFERENCE BT-95 Bartelski & Tatur preprint, CAMK 95-288 GRSV-95 Gluck, Reya, Stratmann & Vogelsang preprint, DO-TH 95/13 GRV-95 Gluck, Reya & Vogelsang preprint, DO-TH 95/11 CLW-95 Cheng, Liu and Wu preprint, IP-ASTP-17-95 BS-95 Bourrely and Soffer Nucl.

The Effect of Positivity Constraints on Polarized Parton Densities
The impact of positivity constraints on the polarized parton densities has been studied. Special attention has been paid to the role of positivity constraints in determining the polarized strange quark and gluon densities, which are not well determined from the present data on inclusive polarized DIS. Spurred on by the famous European Muon Collaboration (EMC) experiment [1] at CERN in 1987, the...
متن کاملStatus of Longitudinal Polarized Parton Densities and Higher Twist
The present status of the longitudinal polarized parton densities (PDFs) and the contribution of their first moments to the nucleon spin is discussed. Special attention is paid to the role of higher twist effects in determining the PDFs and to the polarized strange quark and gluon densities, which are still not well determined from the present data.
متن کاملPolarized Parton Densities in the Nucleon
We present a new NLO QCD analysis of the world data on inclusive polarized deep inelastic scattering. Comparing to our previous analysis: i) the values of gA and a8 = 3F −D are updated ii)the MRST’99 instead of the MRST’98 parametrization for the input unpolarized parton densities is used and iii) the recent SLAC E155 proton data on the spin asymmetry A1 are included in the analysis. A new set ...
متن کاملAn Alternative Approach to Semi-inclusive Dis and a Model Independent Determination of D
We discuss how to extract the polarized parton densities and fragmentation functions in a model independent way from SIDIS, and present results for D + u,d,s. There are two types of processes that give information on polarized parton densities in nucleon. The polarized asymmetry in DIS of longitudinally polarized leptons on longitudinally polarized nucleons: ∆A N = 2y(2− y) 1 + (1− y) ∆σ N σ N ...
متن کاملQ-evolution of Spin-dependent Parton Densities
We discuss the NLO evolution of quark transversity densities and of the parton distribution function for linearly polarized gluons in a linearly polarized hadron. A supersymmetric relation between the NLO evolution kernels for transversity and for linear polarization is found. We also study the implications of NLO evolution for Soffer’s inequality and the prospects of measuring transversity den...
متن کاملRole of Positivity Constraints in Determining Polarized Parton Densities
We have re-analyzed the world data on inclusive polarized DIS, in both NLO and LO QCD, including the very precise JLab Hall A neutron data, and have studied the role of positivity constraints, and demonstrated their importance, in determining the strange and gluon densities. We have shown that higher twist corrections are essential in the analysis of the present data on the structure function g...
