Recent Bcp Progress in Taiwan

The collaboration on B physics and CP violation (BCP) is one of the most active groups in Taiwan. In this talk I will briefly review theoretical progresses on BCP, which were made in Taiwan recently. For experimental review, please refer to Dr. Wang’s talk in this workshop. I will concentrate on five approaches to exclusive B meson decays based on factorization assumption (FA), SU(3) symmetry, perturbative QCD (PQCD) factorization theorem, QCD factorization (QCDF), and light-front QCD (LFQCD) formalism. Abundant results of exclusive B meson decays have been produced and important dynamics has been explored. The effective Hamiltonian for b quark decays, for example, the b → s transition, is given by
