Thermodynamics with Dynamical Clover Fermions
Abstract
We investigate the finite temperature behavior of nonperturbatively improved clover fermions on lattices with temporal extent Nt=4 and 6. Unfortunately in the gauge coupling range, where the clover coefficient has been determined nonperturbatively, the finite temperature crossover/transition occurs at heavy pseudoscalar masses and large pseudoscalar to vector meson mass ratios. However, on an Nt=6 lattice the thermal crossover for the improved fermions is much smoother than for unimproved Wilson fermions and no strange metastable behavior is observed.
