Using three- and four-body decays of D mesons produced in semileptonic b-hadron decays, precision measurements of D meson mass differences are made together with a measurement of the D 0 mass. The ...

A key ingredient to searches for physics beyond the Standard Model in B0 s mixing phenomena is the measurement of the B0 s – B 0 s oscillation frequency, which is equivalent to the mass difference 1ms ...

Using a proton-proton collision data sample corresponding to an integrated luminosity of 3  fb−1 collected by LHCb at center-of-mass energies of 7 and 8 TeV, about 3800 Ξ0b→Ξ+cπ−, Ξ+c→pK−π+ signal decays ...

A measurement of the Ξ++cc mass is performed using data collected by the LHCb experiment between 2016 and 2018 in pp collisions at a centre-of-mass energy of 13 TeV, corresponding to an integrated ...

Charm production at the LHC in pp collisions at √s=7 TeV is studied with the LHCb detector. The decays D0→K−π+,D+→K−π+π+,D∗+→D0(K−π+)π+,D+s→φ(K−K+)π+,Λ+c→pK−π+, and their charge conjugates are analysed ...

Searches are performed for both promptlike and long-lived dark photons, A′, produced in proton-proton collisions at a center-of-mass energy of 13 TeV. These searches look for A′→μ+μ− decays using a data ...

A model-independent search for direct CP violation in the Cabibbo-suppressed decay D+→K−K+π+ in a sample of approximately 370 000 decays is carried out. The data were collected by the LHCb experiment ...

A search for CP violation in the phase space of the decay $D^+\to\pi^-\pi^+\pi^+$ is reported using $pp$ collision data, corresponding to an integrated luminosity of 1.0 fb$^{-1}$, collected by the LHCb ...

A search for direct CP violation in D0 -> h- h+ (where h=K or pi) is presented using data corresponding to an integrated luminosity of 1.0 fb^-1 collected in 2011 by LHCb in pp collisions at a centre-of-mass ...

A search for heavy Majorana neutrinos produced in the B−→π+μ−μ− decay mode is performed using 3  fb−1 of integrated luminosity collected with the LHCb detector in pp collisions at center-of-mass energies ...
