We compute non-perturbatively the renormalisation constants of composite operators on a 163 × 32 lattice with lattice spacing a = 0.093 fm for the overlap fermion action by using the regularisation independent (RI) scheme. The quenched gauge configurations are generated by tadpole improved plaquette plus rectangle action. We test the perturbative continuum relation ZA = ZV and ZS = ZP and find that they agree well above μ = 1.6 GeV. We also perform a Renormalisation Group analysis at the next-to-next-to-leading order and convert the renormalisation constants to the MS scheme.
