We present a lattice QCD calculation of the parameters cx and p which are necessary in the theoretical estimation of the proton lifetime in grand unified theories (GUTS) using chiral lagrangian approach. The simulation is carried out using the Wilson quark action at three gauge coupling constants in
We test the one-loop chiral perturbation theory formula on unquenched lattice data of pseudoscalar meson decay constants. The chiral extrapolation including the effect of the chiral logarithm is attempted and its uncertainty is discussed.
