2+1 flavor QCD calculation of < x > and < x² >

Abstract

We calculate the connected insertions of the nucleon three-point function to study the first few moments of the unpolarized structure functions of the nucleon. (The disconnected insertions are discussed elsewhere in these proceedings). The calculation employs the CP-PACS/JLQCD 2+1 dynamical clover fermions on a 16³ × 32 lattice with lattice spacing a=0.1219 fm. The sequential source technique, using non-zero and zero momentum point nucleon field as the secondary source, is applied enabling a study of different currents at various momentum transfer.
