Abstract

In this paper we study the finite temperature SU(2) gauge theory with staggered fermions for a nonzero imaginary and real chemical potential. The method of analytical continuation of Monte Carlo results from an imaginary to a real chemical potential is tested by comparison with simulations performed directly for a real chemical potential. We discuss the applicability of the method in the different regions of the phase diagram in the temperature-imaginary chemical potential plane.
