Description
We present an evaluation of the quark mass renormalization factor for
Nf=2+1 QCD.
The Schroedinger functional scheme is used as the intermediate scheme.
The regularization independent step scaling function of the quark mass
is evaluated in the continuum limit.
The pseudo scalar density and the axial vector current renormalization
factors are derived for the same action and the bare couplings as
two recent large scale Nf=2+1 simulations of the CP-PACS/JL-QCD
collaboration and that of PACS-CS collaboration.
The quark mass renormalization factor is evaluated to renormalized bare
PCAC masses in these simulations.
