Topological Susceptibility in Nf=2 QCD at Finite Temperature
Abstract
We study the topological charge in Nf=2 QCD at finite temperature using M\"obius domain-wall fermions. The susceptibility 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\ (>Tc) varying the quark mass. A strong suppression of the susceptibility is observed below a certain value of the quark mass. The relation with the restoration of UA(1) is discussed.
