Finite temperature phase transition in full QCD with $N_f=2$ flavors of clover fermions at $N_t=8$ and 10

TL;DR

This paper investigates the finite temperature phase transition in two-flavor QCD using improved Wilson fermions, analyzing the transition temperature and the role of Abelian monopoles in confinement phenomena.

Contribution

It provides the first nonperturbative determination of the transition temperature for N_f=2 QCD with improved Wilson fermions at specific lattice sizes and explores monopole contributions to confinement.

Findings

Transition temperature determined for quark masses 0.6 to 0.8 times the rho mass.

Confirmation of Abelian and monopole dominance in full QCD.

Monopoles significantly contribute to the Polyakov loop and susceptibility.

Abstract

We present results for QCD with $N_f=2$ flavors of dynamical quarks using nonperturbatively 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 $0.6 \lesssim m_\pi/m_\rho \leq 0.8$. After fixing the Maximal Abelian gauge we investigate the contribution of Abelian monopoles to the Polyakov loop, Polyakov loop susceptibility and confirm Abelian and monopole dominance in full QCD.
