A search for the fully reconstructed Bs0-> mu+mu-gamma decay is performed at the LHCb experiment using proton-proton collisions at sqrt{s} = 13 TeV corresponding to an integrated luminosity of 5.4 fb-1.

Abstract
A search for the fully reconstructed Bs0-> mu+mu-gamma decay is performed at the LHCb experiment using proton-proton collisions at sqrt{s} = 13 TeV corresponding to an integrated luminosity of 5.4 fb-1. No significant signal is found and upper limits on the branching fraction in intervals of the dimuon mass are set (Formula presented.) at 95% confidence level. Additionally, upper limits are set on the branching fraction in the [2m_mu, 1.70] GeV/c2 dimuon mass region excluding the contribution from the intermediate Phi(1020) meson, and in the region combining all dimuon-mass intervals.File in questo prodotto:
