Lattice study of finite volume effect in HVP for muon g-2
We report our study of finite volume effect in the leading hadronic contribution to muon g-2 on gauge ensembles with Nf=2+1 dynamical clover fermions generated by PACS collaboration . We compare connected HVP with different physical volumes, from 5.4 -- 8 fm^4, in a fixed lattice spacing a^-1=2.33 GeV in physical pion, We also estimate an extrapolated value into the infinite volume limit and discuss the comparison with chiral perturbation theory.
