Vector Quark Model and B to X_s gamma Decay

Chia-Hung V. Chang, Darwin Chang, Wai-Yee Keung

We study the $B$ meson radiative decay $B \to X_{s} γ$ in the vector quark model. Deviation from the Standard Model arises from the non-unitarity of the charged current KM matrix and…

PQCD study of the $B_{S L}$ and $n_{c}$ controversy in inclusive $B$ decays

Chia-Hung V. Chang, Darwin Chang, We-Fu Chang +2

We calculate the semileptonic branching ratio and the charm counting of inclusive $B$ meson decays using the perturbative QCD formalism. For the nonleptonic decays, we employ the m…
