Critical endpoint in the continuum limit and critical endline at $N_{\mathrm{T}}=6$ of the finite temperature phase transition of QCD with clover fermions

Abstract

We investigate the critical endpoints of the finite temperature phase transition of QCD at zero chemical potential. We employ the renormalization-group improved Iwasaki gauge action and non-perturbatively O(a)-improved Wilson-clover fermion action. The critical endpoints are determined by using the intersection point of kurtosis, employing the multi-parameter, multi-ensemble reweighting method. We present results for the critical endline at $N_{\mathrm{T}}$ = 6 and the continuum extrapolation for the critical endpoint of the SU(3)-flavor symmetric point.
