Abstract The resonant structure of the doubly Cabibbo-suppressed decay D +→K − K + K + is studied for the first time. The measurement is based on a sample of pp-collision data, collected at a centre-of-mass energy of 8 TeV with the …

A measurement of the charm-mixing parameter ${y}_{CP}$ using ${D}^{0}\ensuremath{\rightarrow}{K}^{+}{K}^{\ensuremath{-}}$, ${D}^{0}\ensuremath{\rightarrow}{\ensuremath{\pi}}^{+}{\ensuremath{\pi}}^{\ensuremath{-}}$, and ${D}^{0}\ensuremath{\rightarrow}{K}^{\ensuremath{-}}{\ensuremath{\pi}}^{+}$ decays is reported. The ${D}^{0}$ mesons are required to originate from semimuonic decays of ${B}^{\ensuremath{-}}$ and ${\overline{B}}^{0}$ mesons. These decays are partially reconstructed in a data set of proton-proton collisions …

We report a measurement of the lifetime of the ${\mathrm{\ensuremath{\Omega}}}_{c}^{0}$ baryon using proton-proton collision data at center-of-mass energies of 7 and 8 TeV, corresponding to an integrated luminosity of $3.0\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$ collected by the LHCb experiment. The sample consists of about …

A measurement of the shape of the differential decay rate and the associated Isgur-Wise function for the decay ${\mathrm{\ensuremath{\Lambda}}}_{b}^{0}\ensuremath{\rightarrow}{\mathrm{\ensuremath{\Lambda}}}_{c}^{+}{\ensuremath{\mu}}^{\ensuremath{-}}{\overline{\ensuremath{\nu}}}_{\ensuremath{\mu}}$ is reported, using data corresponding to $3\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$ collected with the LHCb detector in proton-proton collisions. The ${\mathrm{\ensuremath{\Lambda}}}_{c}^{+}{\ensuremath{\mu}}^{\ensuremath{-}}{\overline{\ensuremath{\nu}}}_{\ensuremath{\mu}}(+\mathrm{anything})$ final states are reconstructed …

A search for CP violation in the decay Λ 0 → pK − μ + μ − is presented. This decay is mediated by flavour-changing neutral-current transitions in the Standard Model and is potentially sensitive to new sources of CP violation. The …
