Abstract A first search for the decay is performed by the LHCb experiment with a data sample of proton-proton collisions, corresponding to an integrated luminosity of 9 fb−1 recorded at centre-of-mass energies of 7, 8, and 13 TeV. Two peaking structures are …

The time-dependent $CP$ asymmetries in ${B}^{0}\ensuremath{\rightarrow}{\ensuremath{\pi}}^{+}{\ensuremath{\pi}}^{\ensuremath{-}}$ and ${B}_{s}^{0}\ensuremath{\rightarrow}{K}^{+}{K}^{\ensuremath{-}}$ decays are measured using a data sample of $p$ $p$ collisions corresponding to an integrated luminosity of $3.0\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$, collected with the LHCb detector at center-of-mass energies of 7 and 8 TeV. The …

A search for baryon-number violating ${\mathrm{\ensuremath{\Xi}}}_{b}^{0}$ oscillations is performed with a sample of $pp$ collision data recorded by the LHCb experiment, corresponding to an integrated luminosity of $3\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$. The baryon number at the moment of production is identified by requiring …

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 …

A search for the decays ${B}_{c}^{+}\ensuremath{\rightarrow}J/\ensuremath{\psi}{D}^{(*)0}{K}^{+}$ and ${B}_{c}^{+}\ensuremath{\rightarrow}J/\ensuremath{\psi}{D}^{(*)+}{K}^{*0}$ is performed with data collected at the LHCb experiment corresponding to an integrated luminosity of $3\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$. The decays ${B}_{c}^{+}\ensuremath{\rightarrow}J/\ensuremath{\psi}{D}^{0}{K}^{+}$ and ${B}_{c}^{+}\ensuremath{\rightarrow}J/\ensuremath{\psi}{D}^{*0}{K}^{+}$ are observed for the first time, while first evidence is reported …

The polarization of photons produced in radiative ${B}_{s}^{0}$ decays is studied for the first time. The data are recorded by the LHCb experiment in $pp$ collisions corresponding to an integrated luminosity of $3\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$ at center-of-mass energies of 7 and 8 …
