Charged Higgs on $B^{-} \to τ ν ˉ_{τ}$ and $B ˉ \to P (V) ℓ ν ˉ_{ℓ}$

Chuan-Hung Chen, Chao-Qiang Geng

We study the charged Higgs effects on the decays of $B^{-} \to τ ν ˉ_{τ}$ and $B ˉ \to P (V) ℓ ν ˉ_{ℓ}$ with $P = π^{+}, D^{+}$ and $V = ρ^{+}, D^{*+}$ . We concentrate on the min…

$η^{(')}$ productions in semileptonic B decays

Chuan-Hung Chen, Chao-Qiang Geng

Inspired by the new measurements on $B^{-} \to η^{(')} ℓ ν ˉ_{ℓ}$ from the BaBar Collaboration, we examine the constraint on the flavor-singlet mechanism, proposed to un…

Lepton flavor violation in $τ$ decays

Chuan-Hung Chen, Chao-Qiang Geng

We study the lepton flavor violation (LFV) in tau decays in the framework of the supersymmetric seesaw mechanism with nonholomorphic terms for the lepton sector at a large $tan β$ .…

Production of doubly charmed baryons in B decays

Chuan-Hung Chen

We study the doubly charmed baryonic B decays $B \to Ξ_{c} Λ_{c}$ and $B \to Λ_{c}^{+} Λ_{c}^{-} K$ , recently observed by BELLE. We find that the unexpected large branching ratios (B…
