Semileptonic Decays of $\Lambda \to p{\ell }^{-}{\bar{\nu }}_{\ell }$ in the Light-Front Dynamics

Chong-Chung Lih, Chao-Qiang Geng

We investigate the exclusive semileptonic decays of $\Lambda \to p{\ell }^{-}{\bar{\nu }}_{\ell }(\ell =e,\mu )$ within the Standard Model using the light-front quark model. The transition form facto…
