Finite-temperature QCD with intermediate-large quark masses

Abstract
Hybrid simulations of lattice QCD with four flavors of staggered quarks were performed on a 123×4 lattice for quark masses of 0.1, 0.2, 0.4, and 0.8 (lattice units). The order parameters were measured near the finite-temperature transition. No clear signal of a first-order transition was seen.
