Abstract
We analyze the role of renormalization group (RG) running of the coupling and fermion masses in perturbative Yukawa theory at finite density. The dependence of the RG flow on the number of fermion flavors is discussed. Results for the fermionic contribution to the two-loop pressure at zero temperature and finite density are presented for NF = 4, and finite fermion mass effects are shown to be an important correction.
