Abstract

We study finite-temperature QCD at intermediate values of the bare quark mass m by pseudofermions Monte Carlo for three fermionic flavors on 6³ × 4 and 8³ × 2 lattices. On the 6³ × 4 lattice we study the finite-temperature deconfining and chiral restoration transitions up to values of m for which the critical coupling β_c is the same as the pure gauge case. On the 8³ × 2 lattice we carry on a direct comparison between the pseudofermions method and the hopping parameter expansion for intermediate values of m: we conclude that in this region of values of m the two methods give different results.
