Angular analysis of the rare decay ${\Lambda }_b\to \Lambda (1520)(\to NK){\ell }^{+}{\ell }^{-}$

Sébastien Descotes-Genon, Martín Novoa-Brunet

We study the differential decay rate for the rare decay ${\Lambda }_b\to \Lambda (1520)(\to NK){\ell }^{+}{\ell }^{-}$ where $\ell$ is a light lepton, as this decay mode can provide new and complementary co…
