Dynamically enhanced $B \to K^{*} π$ decays in perturbative QCD

Y. -Y. Keum

We investigate the $B \to K^{*} π$ decays, one of hardly understandable processes among charmless B-meson decays, within the perturbative QCD method. Owing to the dynamically enhanc…

Determination of weak phases $ϕ_{2}$ and $ϕ_{3}$ from $B \to π π, K π$ in the pQCD method

Yong-Yeon Keum

We look at two methods to determine the weak phases $ϕ_{2}$ and $ϕ_{3}$ from $B \to π π$ and $K π$ decays within the perturbative QCD approach. We obtain quite interesting bounds on $ϕ_2…

Possible Large Direct CP Violations in Charmless B-Decays

Y. Y. Keum, A. I. Sanda

We discuss the perturbative QCD approach for the exclusive two body B-meson decays to light mesons. We briefly review its ingredients and some important theoretical issues on facto…

Perturbative QCD analysis of $B \to ϕ K^{*}$ decays

Chuan-Hung Chen, Yong-Yeon Keum, Hsiang-nan Li

We study the first observed charmless $B \to V V$ modes, the $B \to ϕ K^{*}$ decays, in perturbative QCD formalism. The obtained branching ratios $B (B \to ϕ K^{*}) \sim 15 \times 1 0^{- 6}$ are l…

A Novel PQCD Approach in Charmless B-meson Decays

Y. -Y. Keum, H. -N. Li, A. I. Sanda

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 fa…
