The effect of S-wave interference on the $B^0\to K^{\ast 0}{\ell }^{+}{\ell }^{-}$ angular observables

Thomas Blake, Ulrik Egede, Alex Shires

The rare decay $B^0\to K^{\ast 0}{\ell }^{+}{\ell }^{-}$ is a flavour changing neutral current decay with a high sensitivity to physics beyond the Standard Model. Nearly all theoretical pre…
