Search for the Bs0→ μ+μ−γ decay Calvo Gomez, Miriam Golobardes Ribé, Elisabet Vilasis-Cardona, Xavier LHCb Collaboration - CERN Universitat Ramon Llull. La Salle CERN Decay processes Experimental nuclear physics Nuclear physics Particle physics Gran col·lisionador d'hadrons (França i Suïssa) 530.1 539 A search for the fully reconstructed Bs0→ μ+μ−γ decay is performed at the LHCb experiment using proton-proton collisions at 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 [2mμ, 1.70] GeV/c2 dimuon mass region excluding the contribution from the intermediate ϕ(1020) meson, and in the region combining all dimuon-mass intervals. info:eu-repo/semantics/publishedVersion 2020-07-11 info:eu-repo/semantics/article 1029-8479 https://hdl.handle.net/20.500.14342/6085 https://doi.org/10.1007/JHEP07(2024)101 eng Journal of High Energy Physics, 2024. 101 © CERN Attribution 4.0 International http://creativecommons.org/licenses/by/4.0/ info:eu-repo/semantics/openAccess 27 p.
