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…

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…

Bose-Einstein correlations of same-sign charged pions in the forward region in $pp$ collisions at $s$ = 7 TeV

LHCb collaboration, R. Aaij, B. Adeva +805

Bose-Einstein correlations of same-sign charged pions, produced in proton-proton collisions at a 7 TeV centre-of-mass energy, are studied using a data sample collected by the LHCb…

Study of $b b ˉ$ correlations in high energy proton-proton collisions

LHCb collaboration, R. Aaij, B. Adeva +802

Kinematic correlations for pairs of beauty hadrons, produced in high energy proton-proton collisions, are studied. The data sample used was collected with the LHCb experiment at ce…

Updated branching fraction measurements of $B_{(s)}^{0} \to K_{S}^{0} h^{+} h^{' -}$ decays

LHCb collaboration, R. Aaij, B. Adeva +776

The charmless three-body decays $B_{(s)}^{0} \to K_{S}^{0} h^{+} h^{' -}$ (where $h^{(')} = π, K$ ) are analysed using a sample of $pp$ collision dat…

Observation of the doubly charmed baryon $Ξ_{cc}^{++}$

LHCb collaboration, R. Aaij, B. Adeva +805

A highly significant structure is observed in the $Λ_{c}^{+} K^{-} π^{+} π^{+}$ mass spectrum, where the $Λ_{c}^{+}$ baryon is reconstructed in the decay mode $p K^{-} π^{+}$ . The structure is consistent…
