Angular analysis of the rare decay $B_s^0\to \varphi {\mu }^{+}{\mu }^{-}$

Abstract

An angular analysis of the rare decay $B_s^0\to \varphi {\mu }^{+}{\mu }^{-}$ is presented, using proton-proton collision data collected by the LHCb experiment at centre-of-mass energies of $7$, $8$ and $13\mathrm{TeV}$, corresponding to an integrated luminosity of $8.4{\mathrm{fb}}^{-1}$. The observables describing the angular distributions of the decay $B_s^0\to \varphi {\mu }^{+}{\mu }^{-}$ are determined in regions of $q^2$, the square of the dimuon invariant mass. The results are consistent with Standard Model predictions.
