| Research Abstract |
Lattice QCD calculation of phenomenologically important hadronic matrix elements such as the decay constants of pi, K,and B mesons and the B parameter of K meson have been made including the effect of dynamical quarks. Errors caused by finite lattice spacing and finite lattice size are systematically investigated. New numerical method to calculate general multi-correlation function is introduced and is successfully applied to calculate hadronic scattering length, eta'meson mass, pi-NUsigma term, and quark spin content within proton.
