Abstract

We construct a novel Nf=2 pseudofermion action for Monte Carlo simulation of a lattice gauge theory with domain-wall fermions (DWF), which is applicable for all variants of DWF. This new action is particularly useful for the challenging simulations of lattice gauge theories with large Nf=2n DWF, on the large lattices, and in the strong-coupling regime. For the SU(3) lattice gauge theory on the 324 lattice with Nf=10 massless DWF and the Wilson plaquette gauge action at 6/g02=5.70, the efficiency (speed\ifmmode×\else\texttimes\fiacceptance rate) of the hybrid Monte Carlo simulation with the new action is about 1.2 times that of its counterpart with the traditional action.
