Topological susceptibility and QCD phase transition with 2+1 flavor Möbius domain wall fermion at finite temperature
Issaku Kanamori, Yasumichi Aoki, Hidenori Fukaya +3
The topological susceptibility is one of the quantities that has a large discretization error, and the error can be sensitive to the choice of fermion action. We report on our resu…
