摘要：
We present first results for the step scaling function up of the renormalization factor Zp of the pseudoscalar density. The simulations are performed within the framework of the Schrodinger functional with two flavors of O(a) improved Wilson fermions. The knowledge of up is required to compute the renormalization group invariant quark masses. We also study the performance of a variant of the HNIC algorithm using two pseudofermion fields.
