Research Abstract

New knowledge has been obtained regarding search for new physics effects at high luminosity B factory. Especially, methodology of identifying Super symmetric models in B meson decays and possible measurement of lepton-flavor violating tau decays were studies in detail. Also, new research organization has been established to carry out research at the new facility.
