The element |Vcb| of the Cabibbo-Kobayashi-Maskawa matrix is measured using semileptonic Bs0 decays produced in proton-proton collision data collected with the LHCb detector at center-of-mass energies of 7 and 8 TeV, corresponding to an integrated luminosity of 3 fb-1. Rates of Bs0→Ds-μ+νμ …

We report a study of the suppressed B[superscript -] → DK[superscript -]π[superscript +]π[superscript -] and favored B[superscript -] → Dπ[superscript -]π[superscript +]π[superscript -] decays, where the neutral D meson is detected through its decays to the K[superscript ∓]π[superscript ±] and CP-even K[superscript …

The first observation of the B[s over 0] → η[superscript ′]η[superscript ′] decay is reported. The study is based on a sample of proton-proton collisions corresponding to 3.0 fb[superscript -1] of integrated luminosity collected with the LHCb detector. The significance of the …
