The SU(3) phase transitions in the presence of light dynamical quarks

We investigate the deconfinement and the chiral phase transitions in QCD with 3 light dynamical flavors, using the pseudo-fermion method. Monte Carlo simulations have been performed on a lattice of size 8 3 × 4 with fermions of mass 0.1 and 0.075 respectively. A rapid change from the low-temperature...

Description
Summary:We investigate the deconfinement and the chiral phase transitions in QCD with 3 light dynamical flavors, using the pseudo-fermion method. Monte Carlo simulations have been performed on a lattice of size 8 3 × 4 with fermions of mass 0.1 and 0.075 respectively. A rapid change from the low-temperature region of hadrons to the high-temperature quark-gluon plasma is observed in all the physical quantities studied. Our detailed, high-statistics results, however, do not show any signs of a strong first-order transition. In the zero mass limit we find evidence for a chiral phase transition at T c/ Λ L ≅ 183 ± 10.
