title

Nucleon matrix elements for non-perturbatively O(a) improved Wilson fermions

collaboration

QCDSF and UKQCD

abstract

Using non-perturbatively O(a) improved Wilson fermions, results are given
for unpolarised and polarised nucleon matrix elements of local
operators. Particular attention is placed on non-perturbative
renormalisation of the operators. The simulations are performed
for both the quenched theory and two flavours of dynamical fermions.
Where possible, a comparison between these simulations might give some
idea of quenching effects.
