The decay ${\mathrm{\ensuremath{\Lambda}}}_{b}^{0}\ensuremath{\rightarrow}{\ensuremath{\eta}}_{c}(1S)p{K}^{\ensuremath{-}}$ is observed for the first time using a data sample of proton-proton collisions, corresponding to an integrated luminosity of $5.5\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$, collected with the LHCb experiment at a center-of-mass energy of 13 TeV. The branching fraction of the …

Searches are performed for both promptlike and long-lived dark photons, ${A}^{\ensuremath{'}}$, produced in proton-proton collisions at a center-of-mass energy of 13 TeV. These searches look for ${A}^{\ensuremath{'}}\ensuremath{\rightarrow}{\ensuremath{\mu}}^{+}{\ensuremath{\mu}}^{\ensuremath{-}}$ decays using a data sample corresponding to an integrated luminosity of $5.5\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$ collected …
