Description
The chiral quark model consisting of the sigma and pion mesons and the
constituent quarks propagating on the constant background of a temporal
gauge field is solved at finite temperature and baryon chemical potential.
Using an expansion in the number of flavors, both the chiral limit and the
case with physical pion mass are studied. The location of the critical end
point in the mu-T plane is determined using a tree-level fermion propagator and several approximations to the pion propagator.
