First observation of excited $Ω_{b}^{-}$ states

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

We report four narrow peaks in the $Ξ_{b}^{0} K^{-}$ mass spectrum obtained using $pp$ collisions at center-of-mass energies of 7, 8 and 13 TeV, corresponding to a total integrated lumino…

Observation of an excited $B_{c}^{+}$ state

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

Using $pp$ collision data corresponding to an integrated luminosity of $8.5 fb^{- 1}$ recorded by the LHCb experiment at centre-of-mass energies of $s = 7$ , $8$ and…

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…

Amplitude analysis of $B_{s}^{0} \to K_{S}^{0} K^{\pm} π^{\mp}$ decays

LHCb Collaboration, R. Aaij, C. Abellán Beteta +843

The first untagged decay-time-integrated amplitude analysis of $B_{s}^{0} \to K_{S}^{0} K^{\pm} π^{\mp}$ decays is performed using a sample corresponding to $3.0$ …

Measurement of the mass and production rate of $Ξ_{b}^{-}$ baryons

LHCb collaboration, R. Aaij, C. Abellán Beteta +843

The first measurement of the production rate of $Ξ_{b}^{-}$ baryons in $pp$ collisions relative to that of $Λ_{b}^{0}$ baryons is reported, using data samples collected by the LHCb experim…

Measurement of the $B^{\pm}$ production cross-section in pp collisions at $s =$ 7 and 13 TeV

LHCb collaboration, R. Aaij, B. Adeva +796

The production of $B^{\pm}$ mesons is studied in $pp$ collisions at centre-of-mass energies of 7 and 13 TeV, using $B^{\pm} \to J / ψ K^{\pm}$ decays and data samples correspon…
