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…

Search for lepton-universality violation in $B^{+} \to K^{+} ℓ^{+} ℓ^{-}$ decays

LHCb Collaboration, R. Aaij, C. Abellán Beteta +846

A measurement of the ratio of branching fractions of the decays $B^{+} \to K^{+} μ^{+} μ^{-}$ and $B^{+} \to K^{+} e^{+} e^{-}$ is presented. The proton-proton collision data used correspond to an integ…

Observation of $C P$ violation in charm decays

LHCb collaboration, R. Aaij, C. Abellán Beteta +848

A search for charge-parity ( $C P$ ) violation in $D^{0} \to K^{-} K^{+}$ and $D^{0} \to π^{-} π^{+}$ decays is reported, using $pp$ collision data corresponding to an integrated luminosity of…

Measurement of the mass difference between neutral charm-meson eigenstates

LHCb Collaboration, R. Aaij, C. Abellán Beteta +842

We report a measurement of the mass difference between neutral charm-meson eigenstates using a novel approach that enhances sensitivity to this parameter. We use $2.3 \times 1 0^{6}$ $…
