Rare ${\Lambda }_b\to \Lambda l^{+}{l}^{-}$ decay in the Bethe-Salpeter equation approach

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

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