A New Parametrization of Polarized Parton Distribution Functions

الأصل · EN

Requiring the positivity and counting rule, we propose a new parametrization of the polarized parton distribution which reproduce the data well. We found that the NLO analysis is absolutely necessary to extract the correct information on the polarized gluon distributions. The calculated results of xΔdᵥ(x) and Δdᵥ(x)/dᵥ(x) seem to be consistent with the SMC data at Q²=10GeV².
