Updated Analysis of $a_{2} / a_{1}$ in Exclusive B Decays

Hai-Yang Cheng, Kwei-Chou Yang

Using recent experimental data and various theoretical calculations on form factors, we reanalyze the effective parameters $a_{1}$ and $a_{2}$ and their ratio.

Nonfactorizable Effects in Charmless B Decays and B Meson Lifetimes

Hai-Yang Cheng

Status of nonfactorizable effects in hadronic charmless B decays is reviewed. Implications of new CLEO measurements on $B^{0} \to π^{+} π^{-}$ and $B \to η^{'} K$ are discussed. Nonfactorizable…
