Axial U(1) symmetry at high temperature in 2-flavor lattice QCD


  • Dr. Kei SUZUKI

Primary authors



We investigate the axial $U(1)$ symmetry breaking above the critical temperature in 2-flavor lattice QCD whose ensembles are generated with Mobius domain-wall fermions. We will discuss the temperature and quark mass dependence of $U(1)_A$ susceptibility extracted from the spectra of overlap Dirac eigenmodes. The behavior of $U(1)_A$ susceptibility is compared with that of topological susceptibility and their relation will be discussed.
