Abstract

The topological susceptibility is computed in the SU (3) gauge theory at temperatures T above the critical temperature T c using master-field simulations of very large lattices, where the infamous topology-freezing issue is effectively bypassed. Up to T=2.0Tc no unusually large lattice effects are observed and the results obtained in the continuum limit confirm the expected rapid decay of the susceptibility with increasing temperature. As a byproduct, the reference gradient-flow time t is determined in the range of lattice spacings from 0.023 to 0.1fm with a precision of 2 per mille
