Search for $C P$ violation and observation of $P$ violation in $Λ_{b}^{0} \to p π^{-} π^{+} π^{-}$ decays

LHCb collaboration, R. Aaij, C. Abellán Beteta +902

A search for $C P$ violation in the $Λ_{b}^{0} \to p π^{-} π^{+} π^{-}$ decay is performed using LHCb data corresponding to an integrated luminosity of 6.6 $f b^{- 1}$ collected in $pp$ coll…

Measurement of the $B_{c}^{-}$ meson production fraction and asymmetry in 7 and 13 TeV $pp$ collisions

LHCb collaboration, R. Aaij, C. Abellán Beteta +900

The production fraction of the $B_{c}^{-}$ meson with respect to the sum of $B^{-}$ and $B ˉ^{0}$ mesons is measured in both 7 and 13 TeV center-of-mass energy $pp$ collisions produced…

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 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…
