Measurement of $C P$ violation in $B^{0} \to D^{*\pm} D^{\mp}$ decays

LHCb collaboration, R. Aaij, C. Abellán Beteta +901

The decay-time-dependent $C P$ asymmetry in $B^{0} \to D^{*\pm} D^{\mp}$ decays is measured using a data set corresponding to an integrated luminosity of $9$ fb $^{- 1}$ recorded by the L…

Measurement of $f_{s} / f_{u}$ variation with proton-proton collision energy and $B$ -meson kinematics

LHCb collaboration, R. Aaij, C. Abellán Beteta +903

The ratio of the $B_{s}^{0}$ and $B^{+}$ fragmentation fractions $f_{s}$ and $f_{u}$ is studied with $B_{s}^{0} \to J / ψ ϕ$ and $B^+\to\mathrm{J…

Observation of several sources of $C P$ violation in $B^{+} \to π^{+} π^{+} π^{-}$ decays

LHCb collaboration, R. Aaij, C. Abellán Beteta +868

Observations are reported of different sources of $C P$ violation from an amplitude analysis of $B^{+} \to π^{+} π^{+} π^{-}$ decays, based on a data sample corresponding to an integrated l…

Observation of new resonances in the $Λ_{b}^{0} π^{+} π^{-}$ system

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

We report the observation of a new structure in the $Λ_{b}^{0} π^{+} π^{-}$ spectrum using the full LHCb data set of $pp$ collisions, corresponding to an integrated luminosity of $9\,\mathr…
