Differential measurement of the branching fraction and $C P$ asymmetry of the decay $B^{\pm} \to π^{\pm} μ^{+} μ^{-}$

LHCb collaboration, R. Aaij, M. Abdelfatah +1121

Differential measurements of the branching fraction and $C P$ asymmetry of the decay $B^{\pm} \to π^{\pm} μ^{+} μ^{-}$ are performed in intervals of the dimuon mass squared, $q^{2}$ , using pro…
