Measurements of the branching fraction ratio B ϕ → μ + μ − / B ϕ → e + e − with charm meson decays
Measurements of the branching fraction ratio Bϕ→μ+μ−/Bϕ→e+e− with Ds+→π+ϕ and D+→ π+ϕ decays, denoted Rϕπs and Rϕπd, are presented. The analysis is performed using a dataset corresponding to an integrated luminosity of 5.4 fb−1 of pp collision data collected with the LHCb experiment. The branching f...
