Topological Susceptibility in N_f=2 QCD at Finite Temperature

We study the topological charge in N_f=2 QCD at finite temperature using M\"obius domain-wall fermions. The susceptibility \chi_t of the topological charge defined either by the index of overlap Dirac operator or a gluonic operator is investigated at several values of temperature T\ (>T_c) varying the quark mass. A strong... Show more
