Charmful two-body anti-triplet $b$ -baryon decays

Y. K. Hsiao, P. Y. Lin, C. C. Lih +1

We study the charmful decays of the two-body $B_{b} \to B_{n} M_{c}$ decays, where $B_{b}$ represents the anti-triplet of $(Λ_{b}, Ξ_{b}^{0}, Ξ_{b}^{-})$ , $B_{n}$ stands for t…

Semileptonic $B^{-} \to f_{0} (1710, 1500, 1370) e^{-} ν ˉ_{e}$ decays

Y. K. Hsiao, C. C. Lih, C. Q. Geng

We study the semileptonic decays of $B^{-} \to f_{0} (1710, 1500, 1370) e^{-} ν ˉ_{e}$ , in which the three $f_{0}$ states mix with glueball, $s ˉ s$ and $(u ˉ u + d ˉ d) / 2$ st…

Study of Rare $B_{c}^{+} \to D_{d, s}^{(*) +} l l ˉ$ Decays

C. Q. Geng, C. W. Hwang, C. C. Liu

We study the rare decays of $B_{c}^{+} \to D_{q}^{(*) +} l l ˉ$ ( $q = d, s$ and $l = ν_{l}, e, μ, τ)$ in the standard model. The form factors are evaluated in the light front and constituent qua…

Anomaly, Charge Quantization and Family

C. Q. Geng

We first review the three known chiral anomalies in four dimensions and then use the anomaly free conditions to study the uniqueness of quark and lepton representations and charge…

$K_{L} \to γ ν ν ˉ$ in the Light Front Model

C. Q. Geng, C. C. Lih, C. C. Liu

We study the CP conserving and violating contributions to the decay of $\knng$ in the standard model. In our analysis, we use the form factors for $K \to γ$ transitions calculated di…

$τ$ polarization asymmetries in $B^{+} \to τ^{+} ν_{τ} γ$ and $B_{c}^{+} \to τ^{+} ν_{τ} γ$

C. Q. Geng, C. C. Lih, T. H. Wu

We study the lepton polarization asymmetries in the radiative leptonic B decays of $B^{+} \to l^{+} ν_{l} γ$ and $B_{c}^{+} \to l^{+} ν_{l} γ$ . We concentrate on the transverse component of the…

Radiative Leptonic B Decays in the Light Front Model

C. Q. Geng, C. C. Lih, Wei-Min Zhang

Within the light front framework, we calculate the form factors for $B \to γ$ transitions directly in the entire physical range of momentum transfer. Using these form factors, we stu…

T Violating Muon Polarization in $K^{+} \to μ^{+} ν γ$

C. H. Chen, C. Q. Geng, C. C. Lih

We study the T violating transverse muon polarization in the decay of $K^{+} \to μ^{+} ν γ$ due to CP violation in theories beyond the standard model. We find that the polarization asymme…
