Constraints on tensor and scalar couplings from $B\to K\bar{\mu }\mu$ and $B_s\to \bar{\mu }\mu$

Frederik Beaujean, Christoph Bobeth, Stephan Jahn

The angular distribution of $B\to K\bar{\ell }\ell$ ($\ell =e,\mu ,\tau$) depends on two parameters, the lepton forward-backward asymmetry, $A_{\mathrm{FB}}^{\ell }$, and the flat term, $F_H^\…
