Abstract

The interplay of mesonic fluctuations with an axial U(1)AU(1)_A-symmetry breaking and resulting effects on the location of a possibly existing critical endpoint in the QCD phase diagram are investigated in a framework of the functional renormalization group within a Nf=2+1N_f = 2 + 1 flavor quark-meson model truncation. The axial U(1)AU(1)_A-symmetry breaking is imposed by a mesonic Kobayashi-Maskawa-'t Hooft determinant. The quark mass sensitivity of the chiral phase transition with and without the U(1)AU(1)_A-symmetry breaking is studied.
