First measurement of the $C P$ -violating phase $ϕ_{s}^{d d}$ in $B_{s}^{0} \to (K^{+} π^{-}) (K^{-} π^{+})$ decays

LHCb collaboration, R. Aaij, B. Adeva +793

A flavour-tagged decay-time-dependent amplitude analysis of $B_{s}^{0} \to (K^{+} π^{-}) (K^{-} π^{+})$ decays is presented in the $K^{\pm} π^{\mp}$ mass range from 750 to 1600 MeV $/ c^{2}$ . The analys…

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…

Measurement of the $B_{s}^{0} \to μ^{+} μ^{-}$ branching fraction and effective lifetime and search for $B^{0} \to μ^{+} μ^{-}$ decays

LHCb collaboration, R. Aaij, B. Adeva +771

A search for the rare decays $B_{s}^{0} \to μ^{+} μ^{-}$ and $B^{0} \to μ^{+} μ^{-}$ is performed at the LHCb experiment using data collected in $pp$ collisions corresponding to a total integrated lum…

Observation of the decay $Λ_{b}^{0} \to p K^{-} μ^{+} μ^{-}$ and a search for $C P$ violation

LHCb collaboration, R. Aaij, B. Adeva +763

A search for $C P$ violation in the decay $Λ_{b}^{0} \to p K^{-} μ^{+} μ^{-}$ is presented. This decay is mediated by flavour-changing neutral-current transitions in the Standard Model and…
