Description
I will propose a method for studying finite temperature chiral
symmetry restoration, based on a chiral invariant expansion of the
functional renormalization group flows in effective field theories. The
method is capable to recover the one-loop beta-functions of the
U(n)xU(n) linear sigma model, and with calculating the effective
potential, it shows a direct evidence that regardless of the flavor
number, with zero quark masses, the system undergoes a first order
transition. Treatment of the axial anomaly and the finite quark mass
scenario will also be discussed.
