摘要：We summarize the project of the light meson spectrum with Nf =2+1 overlap fermions by the JLQCD and TWQCD collabolations. We study the finite size effect by comparing the analytical correction with the data on a larger volume lattice. Through the chiral extrapolation carried out using data points with the degenerate quark masses mud = ms, we study the convergence property of chiral perturbation theory. With an increased number of data points and modified fit scheme, we update the results of the chiral extrapolation to obtain physical quantities.
