A complete description of P- and S-wave contributions to the $B^0\to K^{+}{\pi }^{-}{\ell }^{+}{\ell }^{-}$ decay

Marcel Algueró, Paula Alvarez Cartelle, Alexander Mclean Marshall +6

In this paper we present a detailed study of the four-body decay $B^0\to K^{+}{\pi }^{-}{\ell }^{+}{\ell }^{-}$, where tensions with the Standard Model predictions have been observed. Our ana…
