Angular distribution of ${\Lambda }_b^0\to p{K}^{-}{\ell }^{+}{\ell }^{-}$ decays comprising $\Lambda$ resonances with spin up to $\le 5/2$

Anja Beck, Thomas Blake, Michal Kreps

This paper describes the angular distribution of ${\Lambda }_b^0\to \Lambda (\to p{K}^{-}){\ell }^{+}{\ell }^{-}$ decays. A full expression is given for the case of multiple interfering spin-states with spin $\…
