Abstract

An angular analysis of the decay Bs0→ ϕe⁺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 TeV. 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, q², corresponding to [0.1, 1.1], [1.1, 6.0] and [15.0, 19.0] GeV²/c⁴. The results are compatible with predictions based on the Standard Model of particle physics.
