Search for the rare decay $B^{0} \to J / ψ ϕ$

LHCb collaboration, R. Aaij, C. Abellán Beteta +962

A search for the rare decay $B^{0} \to J / ψ ϕ$ is performed using $pp$ collision data collected with the LHCb detector at centre-of-mass energies of 7, 8 and 13 TeV, correspond…

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…

Measurements of $C P$ asymmetries in charmless four-body $Λ_{b}$ and $Ξ_{b}^{0}$ decays

LHCb collaboration, R. Aaij, C. Abellán Beteta +841

A search for $C P$ violation in charmless four-body decays of $Λ_{b}$ and $Ξ_{b}^{0}$ baryons with a proton and three charged mesons in the final state is performed. To cancel out product…

Search for lepton-flavour-violating decays of Higgs-like bosons

LHCb collaboration, R. Aaij, C. Abellán Beteta +835

A search is presented for a Higgs-like boson with mass in the range 45 to 195 GeV/ $c^{2}$ decaying into a muon and a tau lepton. The dataset consists of proton-proton interactions at…

Measurement of the ratio of branching fractions $B (B_{c}^{+} \to J / ψ τ^{+} ν_{τ})$ / $B (B_{c}^{+} \to J / ψ μ^{+} ν_{μ})$

LHCb collaboration, R. Aaij, B. Adeva +797

A measurement is reported of the ratio of branching fractions $R (J / ψ) = B (B_{c}^{+} \to J / ψ τ^{+} ν_{τ}) / B (B_{c}^{+} \to J / ψ μ^{+} ν_{μ})$ , where the $τ^{+}$ lepton is id…
