A practical solution to the sign problem at finite theta-vacuum angle (1208.0375v1)
Published 1 Aug 2012 in hep-ph, hep-lat, and nucl-th
Abstract: We propose a practical way of circumventing the sign problem in lattice QCD simulations with a theta-vacuum term. This method is the reweighting method for the QCD Lagrangian after the U_A(1) transformation. In the Lagrangian, the P-odd mass term as a cause of the sign problem is minimized. In order to find out a good reference system in the reweighting method, we estimate the average reweighting factor by using the two-flavor NJL model and eventually find a good reference system.
