Angular analysis of the $B^{+} \to π^{+} μ^{+} μ^{-}$ decay

LHCb collaboration, R. Aaij, M. Abdelfatah +1112

This paper presents the first measurement of the forward-backward asymmetry, $A_{FB}$ , and the flat term, $F_{H}$ , that parameterise the angular distribution of the $B^+\toπ^+μ…

Search for $D^{*} (2007)^{0} \to μ^{+} μ^{-}$ in $B^{-} \to π^{-} μ^{+} μ^{-}$ decays

LHCb collaboration, R. Aaij, A. S. W. Abdelmotteleb +1047

The very rare $D^{*} (2007)^{0} \to μ^{+} μ^{-}$ decay is searched for by analysing $B^{-} \to π^{-} μ^{+} μ^{-}$ decays. The analysis uses a sample of beauty mesons produced in proton-proton collisions…
