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

Abstract

An angular analysis of the decay $B_s^0\to \varphi e^{+}{e}^{-}$ is presented, using proton-proton collision data collected with the LHCb detector between 2011 and 2018 at centre-of-mass energies of 7, 8 and 13$\mathrm{Te}\mathrm{V}$. The combined dataset corresponds to an integrated luminosity of $9{\mathrm{fb}}^{-1}$. Observables are determined by fitting time-integrated projections of the angular distribution in three bins of dielectron mass squared, $q^2$, corresponding to $[0.1,1.1]$, $[1.1,6.0]$ and $[15.0,19.0]{\mathrm{Ge}\mathrm{V}}^2/c^4$. The results are compatible with predictions based on the Standard Model of particle physics.
