Determination of quantum numbers for several excited charmed mesons observed in $B^{-} \to D^{*+} π^{-} π^{-}$ decays

LHCb collaboration, R. Aaij, C. Abellán Beteta +907

A four-body amplitude analysis of the $B^{-} \to D^{*+} π^{-} π^{-}$ decay is performed, where fractions and relative phases of the various resonances contributing to the decay are measu…

Updated measurement of decay-time-dependent CP asymmetries in $D^{0} \to K^{+} K^{-}$ and $D^{0} \to π^{+} π^{-}$ decays

LHCb collaboration, R. Aaij, C. Abellán Beteta +910

A search for decay-time-dependent charge-parity ( $C P$ ) asymmetry in $D^{0} \to K^{+} K^{-}$ and $D^{0} \to π^{+} π^{-}$ decays is performed at the LHCb experiment using proton-proton collision d…

LHCb collaboration, R. Aaij, C. Abellán Beteta +866

A narrow pentaquark state, $P_{c} (4312)^{+}$ , decaying to $J / ψ p$ is discovered with a statistical significance of $7.3 σ$ in a data sample of $Λ_{b}^{0} \to J / ψ p K^{-}$ decays which is an or…
