We analyze the pseudocritical behavior of three-flavor QCD using highly improved staggered quarks on lattices with temporal extent N�=8 and for quark masses corresponding to a pseudoscalar Goldstone mass in the range 80 MeV m� 140 MeV. Our findings are consistent with the occurrence of a second order chiral phase transition at vanishing values of the quark masses. The chiral phase transition temperature at this finite value of the lattice spacing is determined to be Tc=98-6+3 MeV. A comparison with a corresponding analysis performed in (2+1)-flavor QCD suggests that the continuum limit extrapolated chiral phase transition temperature in three-flavor QCD will turn out to be below 90 MeV. © 2022 authors.
