Abstract

We report on a study of the finite-temperature chiral transition on an N_t=4 lattice for 2+1 flavors of Kogut-Susskind quarks. We find the point of physical quark masses to lie in the region of crossover, in agreement with results of previous studies. Results of a detailed examination of the m_u,d=m_s case indicate vanishing of the screening mass of σ meson at the end point of the first-order transition.
