The first observation of the ${B}_{s}^{0}\ensuremath{\rightarrow}{\ensuremath{\eta}}^{\ensuremath{'}}{\ensuremath{\eta}}^{\ensuremath{'}}$ decay is reported. The study is based on a sample of proton-proton collisions corresponding to $3.0\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$ of integrated luminosity collected with the LHCb detector. The significance of the signal is 6.4 standard deviations. The …

The first observation of the B 0 → D ∗ ∓ K ± decay is reported using 3.0 fb−1 of proton-proton collision data collected by the LHCb experiment. The D ∗ ∓ mesons are reconstructed through the decay chain D ∗ ∓ …

The semileptonic $CP$ asymmetry in ${B}^{0}$-${\overline{B}}^{0}$ mixing, ${a}_{\text{sl}}^{d}$, is measured in proton-proton collision data, corresponding to an integrated luminosity of $3.0\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$, recorded by the LHCb experiment. Semileptonic ${B}^{0}$ decays are reconstructed in the inclusive final states ${D}^{\ensuremath{-}}{\ensuremath{\mu}}^{+}$ and ${D}^{*\ensuremath{-}}{\ensuremath{\mu}}^{+}$, where …

We report on measurements of the mass and lifetime of the ${\mathrm{\ensuremath{\Xi}}}_{b}^{\ensuremath{-}}$ baryon using about 1800 ${\mathrm{\ensuremath{\Xi}}}_{b}^{\ensuremath{-}}$ decays reconstructed in a proton-proton collision data set corresponding to an integrated luminosity of $3.0\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$ collected by the LHCb experiment. The decays are …
