QCD Analysis of Polarized Scattering Data and New Polarized Parton Distributions

High Energy Physics - Phenomenology 2009-09-29 v1

Abstract

In this talk results from a new QCD analysis in leading (LO) and next--to--leading (NLO) order are presented. New parametrizations of the polarized quark and gluon densities are derived together with parametrizations of their fully correlated 1σ\sigma error bands. Furthermore the value of αs(MZ2)\alpha_s(M_Z^2) is determined. Finally a number of low moments of the polarized parton densities are compared with results from lattice simulations.
