Parametrization of polarized parton distribution functions
Abstract
Polarized parton distribution functions are determined by using asymmetry A1 data from longitudinally polarized deep inelastic scattering experiments. From our 2 analysis, polarized u-valence, d-valence, antiquark, and gluon distributions are obtained. We propose one set of leading-order distributions and two sets of next-to-leading-order ones as the longitudinally-polarized parton distribution functions.
