Measurement of the Forward-Backward Asymmetry in the B -> K(*) mu+ mu- Decay and First Observation of the Bs -> phi mu+ mu- Decay

CDF Collaboration, T. Aaltonen

We reconstruct the rare decays $B^{+}\to K^{+}{\mu }^{+}{\mu }^{-}$, $B^0\to K^{\ast }(892{)}^0{\mu }^{+}{\mu }^{-}$, and $B_s^0\to \varphi (1020){\mu }^{+}{\mu }^{-}$ in a data sample corresponding to $4.4\mathrm{f}{\mathrm{b}}^{-1}$ collected in $…
