Search for the B s 0 → μ + μ − γ decay

عرض إصدارات أخرى (1)

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...

الوصف
الملخص: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 setBBs0→μ+μ−γ<4.2×10−8, mμ+μ−∈2mμ1.70GeV/c2, BBs0→μ+μ−γ<7.7×10−8, mμ+μ−∈1.70, 2.88GeV/c2, BBs0→μ+μ−γ<4.2×10−8, mμ+μ−∈3.92mBs0GeV/c2, 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.
