An angular analysis of the decay B0s → ϕ 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 13TeV.

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] GeV^2/c^4. The results are compatible with predictions based on the Standard Model of particle physics.

Abstract

An angular analysis of the decay B0s → ϕ 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 13TeV. The combined dataset corresponds to an integrated luminosity of 9 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] GeV^2/c^4. The results are compatible with predictions based on the Standard Model of particle physics.
