چکیده
I review important aspects of the perturbative QCD approach to exclusive B meson decays, concentrating on factorization theorem , gauge invariance, end-point singularities, k T and threshold resummations, power counting, penguin enhancement, and CP asymmetries.

PQCD analysis of exclusive B meson decays
Recently, perturbative QCD (PQCD) has been proposed to be an alternative approach to the study of heavy hadron decays [1{3], which complements the heavy quark e ective theory (HQET) [4] for inclusive processes and the Bauer-Stech-Wirbel (BSW) method [5] for exclusive processes. The basic idea is the factorization theorem, which states that nonperturbative dynamics involved in a physical quantit...
متن کاملPQCD approach to exclusive B decays
I review the recent progress on the perturbative QCD approach to exclusive B meson decays, discussing the comparison of collinear and kT factorizations, the CP asymmetry in the B → ππ decay, penguin enhancement, the branching ratio of the B → Dπ decay, and three-body nonleptonic decays.
متن کاملA Novel PQCD Approach in Charmless B - meson Decays
We discuss a novel pertubative QCD approach on the exclusive non-leptonic two body B-meson decays. We briefly review its ingredients and some important theoretical issues on the factorization approaches. We show numerical results which is compatible with recent experimantal data for the charmless B-meson decays.
متن کاملExclusive Decays of B → K ( ∗ ) l + l − in the PQCD
We study the exclusive decays of B → Kll within the framework of the PQCD. We obtain the form factors for the B → K transitions in all allowed values of q, which agree with the lattice results. We find that our distributions of the decay rates and leptonic asymmetries are consistent with that given in the other QCD models in the literature.
متن کاملRecent 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, ...
