Finite Temperature Phase Transition for Three Flavor QCD with Möbius-domain Wall Fermions

The nature of the finite temperature phase transition in (2+1)-flavor QCD depends on the quark mass, and the order and universal class of the phase transition are shown in a diagram called the Columbia plot.The region of light quark masses in this diagram is not yet fully understood.We present preliminary results of a three-flavor QCD study using Möbius-domain wall fermions to search for the critical endpoint in the light quark mass region on the diagonal line of the Columbia plot.
