# Topological susceptibility in finite-temperature (2+1)-flavor QCD with gradient flow

## Speakers

• Prof. Kazuyuki KANAYA

## Content

We study the temperature-dependence of the topological susceptibility, determined in (2+1)-flavor QCD with improved Wilson quarks. To calculate the topological charge and its susceptibility, we adopt the gradient flow method. With heavy up and down quarks ($m_{\rm PS}/m_V \approx 0.63$) and approximately physical strange quark, we study in the range $T=174-697$ MeV.
