Findings

Transition temperature determined for quark masses 0.6<m_pi/m_rho<0.8

Extrapolation to continuum and chiral limits performed

Discussion on the order of the QCD phase transition

Abstract

We present results obtained in QCD with two flavors of non-perturbatively improved Wilson fermions at finite temperature on $16^3 \times 8$ and $24^3 \times 10$ lattices. We determine the transition temperature in the range of quark masses $0.6<m_\pi/m_\rho<0.8$ at lattice spacing a$\approx$0.1 fm and extrapolate the transition temperature to the continuum and to the chiral limits. We also discuss the order of phase transition.
