含有三叶草费米子的QCD有限温度相变的连续极限临界端点和$N_{\rm T}=6$临界端点
Critical endpoint in the continuum limit and critical endline at $N_{\rm T}=6$ of the finite temperature phase transition of QCD with clover fermions
摘要：
研究了零化学势下QCD有限温度相变的临界端点。我们采用重整化群改进的Iwasaki规范作用量和非微扰O（a）改进的Wilson-clover费米子作用量。采用多参数、多集合重加权方法，利用峰度交点确定关键端点。我们给出了$N_{\rm T}$ = 6时临界端点的结果和SU（3）味对称点临界端点的连续外推。
英文摘要：
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 $N_{\rm T}$ = 6 and the continuum extrapolation for the critical endpoint of the SU(3)-flavor symmetric point.
