Polarized leptoproduction and dynamically generated spin-dependent parton distributions
Description
The first moment of the polarized parton distributions of the proton is evaluated dynamically using the assumption that at some low resolution scale the proton consists of valence quarks only. The spin carried by gluons, ΔG, at the EMC resolution scale Q02=10 GeV2 is predicted to be ΔG/sp≅5 with sp=1/2 denoting the spin of the proton. This result furthermore explains the dynamical origin of the recent EMC measurement of the first moment of the polarized structure function g1P(x, Q2). (orig.)
