Forward-backward asymmetries in $Λ_{b} \to Λ l^{+} l^{-}$ in Bethe-Salpeter equation approach

Liang-Liang Liu, Su-Jun Cui, Jing Xu +1

Using the Bethe-Salpeter equation (BSE) we investigate the forward-backward asymmetries $(A_{F B})$ in $Λ_{b} \to Λ l^{+} l^{-} (l = e, μ, τ)$ in the quark-diquark model. This approac…

FCNC transitions of $Λ_{b}$ to neutron in Bethe-Salpeter equation approach

Liang-Liang Liu, Chao Wang, Xian-Wei Kang +1

In a covariant quark-diquark model, we investigate the rare decay of $Λ_{b} \to n l^{+} l^{-}$ and $Λ_{b} \to nγ$ in the Bethe-Salpeter equation approach. In this model th…

Rare $Λ_{b} \to Λ l^{+} l^{-}$ decay in the Bethe-Salpeter equation approach

Liang-Liang Liu, Xian-Wei Kang, Zhen-Yang Wang +1

We study the rare decays $Λ_{b} \to Λ l^{+} l^{-} (l = e, μ, τ)$ in the Bethe-Salpeter equation approach. We find that depending on the values of parameters in our model the branchin…

Electromagnetic form factors of $Λ_{c}$ in the Bethe-Salpeter equation approach

Liang-Liang Liu, Chao Wang, Xin-Heng Guo

We study the electromagnetic form factors (EMFFs) of $Λ_{c}$ and the quark and diquark current contributes to the EMFFs of $Λ_{c}$ in the space-like (SL) region in the Bethe-Salpeter e…

Possible open-charmed pentaquark molecule $Ω_{c} (3188)$ --- the $D Ξ$ bound state --- in the Bethe-Salpeter formalism

Chao Wang, Liang-Liang Liu, Xian-Wei Kang +2

We study the $S$ -wave $D Ξ$ bound state in the Bethe-Salpeter formalism in the ladder and instantaneous approximations. With the kernel generated by the hadronic effective Lagrangia…

Electromagnetic form factors of $Λ_{b}$ in the Bethe-Salpeter equation approach

Liang-Liang Liu, Chao Wang, Ying Liu +1

The heavy baryon $Λ_{b}$ is regarded as composed of a heavy quark and a scalar diquark which has good spin and isospin quantum numbers. In this picture, we calculate the electromagn…
