Axial U(1) symmetry near the pseudocritical temperature in $N_f=2+1$ lattice QCD with chiral fermions

Sinya Aoki, Yasumichi Aoki, Hidenori Fukaya +7

We study the $U(1{)}_A$ anomaly at high temperatures of $N_f=2+1$ lattice QCD with chiral fermions. Gauge ensembles are generated with Möbius domain-wall (MDW) fermions, and the meas…
