Topological Susceptibility in Nf = 2 QCD at Finite Temperature

Topological Susceptibility in Nf = 2 QCD at Finite Temperature

We study the topological charge in Nf = 2 QCD at finite temperature using Möbius domain-wall fermions. The susceptibility Xt 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 (> Tc) varying the...
