摘要：We consider 2+1 flavor Wilson chiral perturbation theory including the lattice spacing contributions of O(a2). We adopt a power counting which the O(a2) terms are included in a leading order. Here, we present a result of the pseudo scalar meson masses to one loop. The mass formulae are required to perform the chiral extrapolation of the CP-PACS/JLQCD lattice data.
