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…

Measurement of the $B^{\pm}$ production asymmetry and the $C P$ asymmetry in $B^{\pm} \to J / ψ K^{\pm}$ decays

LHCb collaboration, R. Aaij, B. Adeva +764

The $B^{\pm}$ meson production asymmetry in $pp$ collisions is measured using $B^{+} \to D ˉ^{0} π^{+}$ decays. The data were recorded by the LHCb experiment during Run 1 of the LHC…

Observation of $B_{c}^{+} \to J / ψ D^{()} K^{()}$ decays

LHCb collaboration, R. Aaij, B. Adeva +764

A search for the decays $B_{c}^{+} \to J / ψ D^{(*) 0} K^{+}$ and $B_{c}^{+} \to J / ψ D^{(*) +} K^{* 0}$ is performed with data collected at the LHCb experiment corresponding to an integrated lumino…

Search for structure in the $B_{s}^{0} π^{\pm}$ invariant mass spectrum

LHCb collaboration, R. Aaij, B. Adeva +761

The $B_{s}^{0} π^{\pm}$ invariant mass distribution is investigated in order to search for possible exotic meson states. The analysis is based on a data sample recorded with the LHCb dete…

Observation of the $Λ_{b}^{0} \to J / ψ p π^{-}$ decay

LHCb collaboration, R. Aaij, B. Adeva +702

The first observation of the Cabibbo-suppressed decay $Λ_{b}^{0} \to J / ψ p π^{-}$ is reported using a data sample of proton-proton collisions at 7 and 8 TeV, corresponding to an in…

Measurement of CP violation parameters in B0->D K*0 decays

LHCb collaboration, R. Aaij, B. Adeva +698

An analysis of B0->D K*0 decays is presented, where D represents an admixture of D0 and D0b mesons reconstructed in four separate final states: K-pi+, pi-K+, K+K- and pi+pi-. The d…
