Abstract

Binder-cumulant analysis of the critical point in the heavy-quark region of QCD is performed by Monte-Carlo simulations with the hopping-parameter expansion at N_t=6. We extend our previous analysis at N_t=4 to finer lattices and perform high-precision analyses on large spatial volumes up to the aspect ratio LT=N_s/N_t=18. Higher order terms in the hopping-parameter expansion are incorporated effectively up to 14th order. The numerical results show that the violation of the finite-size scaling becomes more prominent on the finer lattice at a given aspect ratio.
