Abstract:

Moments of the quark density distribution, moments of the quark helicity distribution, and the tensor charge are calculated in full QCD. Calculations of matrix elements of operators from the operator product expansion have been performed on

16^3 \times 32

lattices for Wilson fermions at

\beta = 5.6

using configurations from the SESAM collaboration and at

\beta = 5.5

using configurations from SCRI. One-loop perturbative renormalization corrections are included. Selected results are compared with corresponding quenched calculations and with calculations using cooled configurations.
