Search for the Bs0→ μ+μ−γ decay

Aaij, R. ; Ruiz-Vidal, Joan LU and Zunica, G. (2024) In Journal of High Energy Physics 2024(7).
Abstract
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. © The Author(s) 2024.
