Comments on the Quark Content of the Scalar Meson $f_{0} (1370)$

Hai-Yang Cheng

Based on the measurements of $(D_{s}^{+}, D^{+}) \to f_{0} (1370) π^{+}$ we determine, in a model independent way, the allowed $s s ˉ$ content in the scalar meson $f_{0} (1370)$ . We find that, on…

Threshold resummation for nonleptonic B meson decays

Hsiang-nan Li, Kazumasa Ukai

We investigate the double logarithmic corrections $α_{s} ln^{2} x$ , x being a parton momentum fraction, in two-body nonleptonic B meson decays in collinear factorization theorem of per…

$B \to f_{0} (980) K^{(*)}$ decays and final state interactions

Chuan-Hung Chen

We study the exclusive decays of $B \to f_{0} (980) K^{(*)}$ in the framework of the perturbative QCD by identifying the $f_{0} (980)$ as the composition of $s ˉ s$ and $\bar{n}n=…

Hadronic B Decays to Charmed Baryons

Hai-Yang Cheng, Kwei-Chou Yang

We study exclusive B decays to final states containing a charmed baryon within the pole model framework. Since the strong coupling for $Λ_{b} B ˉ N$ is larger than that for $Σ_b \b…

$k_{T}$ factorization of exclusive processes

Makiko Nagashima, Hsiang-nan Li

We prove $k_{T}$ factorization theorem in perturbative QCD (PQCD) for exclusive processes by considering $π γ^{*} \to γ (π)$ and $B \to γ (π) l ν ˉ$ . The relevant form factors are expressed…

PQCD approach to exclusive B decays

Hsiang-nan Li

I review the recent progress on the perturbative QCD approach to exclusive $B$ meson decays, discussing the comparison of collinear and $k_{T}$ factorizations, the CP asymmetry in th…
