The $Λ_{b} \to J / ψ + Λ$ Decay Revisited

Hai-Yang Cheng, B. Tseng

The $\b$ decay does not receive any nonspectator contributions and hence its theoretical calculation is relatively clean. Two different methods are employed for the study of $\b$.…

Extraction of $a_{1}$ and $a_{2}$ from $B \to ψ K (K^{}), D (D^{}) π (ρ)$ Decays

Hai-Yang Cheng, B. Tseng

Based on the factorization approach, we show that the CLEO data for the ratio $Γ (B \to ψ K^{*}) /Γ (B \to ψ K)$ and the CDF measurement of the fraction of longitudinal polarization in $B\to…
