Abstract

I present a numerical study of the crossover between the low temperature chirally broken phase and the high temperature chirally restored phase in SU(Nc)SU(N_c) gauge theory with Nc=35N_c=3-5 colors and Nf=2N_f=2 degenerate fermion flavors. Fermion masses span a range of intermediate values (represented by the squared ratio of pseudoscalar to vector meson masses (mPS/mV)20.25(m_{PS}/m_V)^2\sim 0.25 to 0.63). Observables include the temperature dependent chiral condensate and screening masses. At each fermion mass these quantities show nearly identical temperature dependence across NcN_c.
