Description

We present a systematic study of finite size correction and cut-off effect in hadronic vacuum polarization contribution to muon g-2 with two volumes, 5.4 fm$^3$ and 10.8 fm$^3$, and two lattice cut-off, 2.33 GeV and 3.06 GeV, at the physical pion on the PACS configuration. In this analysis, using high statistics data, we compare two volumes at long-distance on the physical point to directly estimate the finite size correction, and it then makes a comparison with ChPT prediction. Using the different cut-off scales on ~10.8 fm$^3$ lattice box, we try to estimate the cut-off effect with local and point-splitting operators on the two cut-off configurations.
