$Λ_{b} \to p, Λ$ transition form factors from QCD light-cone sum rules

Yu-Ming Wang, Yue-Long Shen, Cai-Dian Lu

Light-cone sum rules for the $Λ_{b} \to p, Λ$ transition form factors are derived from the correlation functions expanded by the twist of the distribution amplitudes of $Λ_{b}$ baryon.…

Exclusive $B_{s}$ decays to the charmed mesons $D_{s}^{+} (1968, 2317)$ in the standard model

Run-Hui Li, Cai-Dian Lu, Yu-Ming Wang

The transition form factors of $B ˉ_{s}^{0} \to D_{s}^{+} (2317)$ and $B ˉ_{s}^{0} \to D_{s}^{+} (1968)$ at large recoil region are investigated in the light cone sum rules approach, where the…

FCNC-induced semileptonic decays of $J / ψ$ in the Standard Model

Yu-Ming Wang, Hao Zou, Zheng-Tao Wei +2

In this work, we calculate the form factors for $J / ψ \to D ˉ^{(*) 0}$ induced by the flavor changing neutral currents (FCNC) in terms of the QCD sum rules. Making use of these fo…

Exclusive semileptonic decays of $Λ_{b} \to Λ l^{+} l^{-}$ in supersymmetric theories

M. Jamil Aslam, Yu-Ming Wang, Cai-Dian Lu

The weak decays of $Λ_{b} \to Λ l^{+} l^{-}$ ( $l = e, μ$ ) are investigated in Minimal Supersymmetric Standard Model (MSSM) and also in Supersymmetric (SUSY) SO(10) Grand Unified Models.…

Charmless Two-body $B (B_{s}) \to P P, V P$ decays In Soft-Collinear-Effective-Theory

Wei Wang, Yu-Ming Wang, De-Shan Yang +1

We analyze the charmless two-body $B \to V P$ decays in the soft-collinear-effective-theory (SCET), where $V (P)$ denotes a light vector (pseudoscalar) meson. Using the current experi…

Lifetime of doubly charmed baryons

Chao-Hsi Chang, Tong Li, Xue-Qian Li +1

In this work, we evaluate the lifetimes of the doubly charmed baryons $Ξ_{cc}^{+}$ , $Ξ_{cc}^{++}$ and $Ω_{cc}^{+}$ . We carefully calculate the non-spectator contributions at the qu…
