The difficulty in the decay constants and spectra of $D_{s J}^{*}$

Ron-Chou Hsieh, Chuan-Hung Chen, Chao-Qiang Geng

We examine the compatibility in predicted masses and the decay constants of $D_{s J}^{*}$ mesons in terms of two-quark contents. We find that the results of a specific model, which…

Tau Radiative Decays in the Light Front Quark Model

C. Q. Geng, C. C. Lih

We study the decays of $τ^{-} \to ν_{τ} P^{-} γ (P = π^{-}, K^{-})$ in the light front quark model. We calculate the form factors and use them to evaluate the decay widths. We find that, in the…

Axial-vector Form Factors for $K_{ℓ 2 γ}$ and $π_{ℓ 2 γ}$ at $O (p^{6})$ in Chiral Perturbation Theory

C. Q. Geng, I-Lin Ho, T. H. Wu

We present two-loop calculations on the axial-vector form factors $F_{A}$ of semileptonic radiative kaon and pion decays in chiral perturbation theory. The relevant dimension-6 terms…

Study of $B_{s} \to (η, η^{'}, ϕ) ℓ ℓ ˉ$ Decays

C. Q. Geng, C. C. Liu

We study the rare decays of $B_{s} \to M_{s} ℓ ℓ ˉ$ ( $M_{s} = η, η^{'}, ϕ$ and $ℓ = ν, e, μ, τ$ ) in the standard model. With the hadronic form factors evaluated in the light front and…

Forward-backward Asymmetry in $K^{+} \to π^{+} ℓ^{+} ℓ^{-}$

Chuan-Hung Chen, C. Q. Geng, I-Lin Ho

We study the forward-backward asymmetries in the decays of $K^{+} \to π^{+} ℓ^{+} ℓ^{-}$ ( $ℓ = e$ and $μ$ ) in the presence of scalar or tensor terms. We find that with the scalar (tens…
