As a contribution to the ongoing discussion on the question of a critical endpoint of a chiral phase transition, a nucleon-meson model was studied recently [1]. There was no evidence of a critical phase transition in the region of chemical freeze-out for larger chemical potential. We try to extend and solidify the calculations that were done at the mean field level by including mesonic fluctuations with help of the functional renormalization group equations.
