Continuum Extrapolation of Moments of Nucleon Quark Distributions in Full QCD

Abstract

Moments of light cone quark density, helicity, and transversity distributions are calculated in unquenched lattice QCD at ${\hat{I}}^2=5.5$ and ${\hat{I}}^2=5.3$ using Wilson fermions on $16^3\times 32$ lattices. These results are combined with earlier calculations at ${\hat{I}}^2=5.6$ using SESAM configurations to study the continuum limit.
