Looking for forward backward asymmetries in $B \to K μ^{+} μ^{-}$ and $K^{+} \to π^{+} μ^{+} μ^{-}$

Chuan-Hung Chen, Chao-Qiang Geng, Anjan K. Giri

We investigate the possibility of scalar interaction affecting the forward backward asymmetry in the decay mode $B \to K μ^{+} μ^{-}$ . Using the scalar contribution and advocating Cheng…

Productions of $K_{0}^{*} (1430)$ and $K_{1}$ in B decays

Chuan-Hung Chen, Chao-Qiang Geng, Yu-Kuo Hsiao +1

We study the productions of p-wave mesons $K_{0}^{*} (1430)$ , $K_{1} (1270)$ and $K_{1} (1400)$ in B decays. By the generalized factorization approach, we find that the branching ratios…

Scalar interactions and the polarizations of $B \to ϕ K^{*}$

Chuan-Hung Chen, Chao-Qiang Geng

We try to understand the polarization puzzle in $B \to ϕ K^{*}$ decays with a simple Higgs model associated with flavor changing neutral current at tree level. The new interactions can…

Some Tests on CPT Invariance

C. Q. Geng, Lei Geng

We first briefly review tests on CPT invariance based on the consequences of the CPT theorem and then present some possible CPT tests due to exotic models in which some of the CPT…

Lepton angular asymmetries in semileptonic charmful B decays

Chuan-Hung Chen, Chao-Qiang Geng

We study the lepton angular distributions in $B \to D^{(*)} ℓ ν_{ℓ}$ decays. The lepton angular asymmetries in the decays with the general effective interactions are examined.…

Probe the effects of split SUSY in rare B decays

Chuan-Hung Chen, Chao-Qiang Geng

We study the decays of $B \to K^{(*)} ℓ^{+} ℓ^{-}$ in split supersymmetry with R-parity violation. We find that the decay branching ratio of $B \to K τ^{+} τ^{-}$ in the new physics…
