Study of $W$ boson production in association with beauty and charm

LHCb collaboration, R. Aaij, B. Adeva +722

The associated production of a $W$ boson with a jet originating from either a light parton or heavy-flavor quark is studied in the forward region using proton-proton collisions. Th…

Dalitz plot analysis of $B^{0} \to D^{0} π^{+} π^{-}$ decays

LHCb collaboration, R. Aaij, B. Adeva +710

The resonant substructures of $B^{0} \to D^{0} π^{+} π^{-}$ decays are studied with the Dalitz plot technique. In this study a data sample corresponding to an integrated luminosi…
