I review the known approaches to two-body nonleptonic B meson decays, including factorization assumption, modified factorization assumption, QCD factorization, and perturbative QCD factorization. Important phenomenological aspects of these approaches are emphasized.

We calculate branching ratios for pure penguin decay modes, B → φK decays using perturbative QCD approach. Our results of branching ratios are consistent with the experimental data and larger than those obtained from the naive factorization assumption and the QCD-improved factorization approach. This is due to a dynamical penguin enhancement in perturbative QCD approach. PACS index : 13.25.Hw, ...

I briefly introduce the theoretical frameworks for studies of two-body hadronic B meson decays, which include the factorization assumption, the QCD-improved factorization, the perturbative QCD, the soft-collinear effective theory, the light-cone QCD sum rules, and the quark-diagram parametrization.

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, ...
