Description
We investigate finite size effect on hadron masses and decay constants using a subset of the PACS10 configurations which are generated keeping the space-time volumes over (10 fm)^4 at the physical point in 2+1 flavor QCD with the Wilson-type quarks. We have tried two kinds of analyses fixing the $\kappa$ values or the measured axial Ward identity quark masses. The finite size effect is discussed by comparing the results on (5.4 fm)^4 and (10.8 fm)^4 lattices at the cutoff scale of 1/a=2.333 GeV with emphasis on the pseudoscalar meson sector and the Omega baryon.
