The production of J/ψ mesons accompanied by open charm hadrons, and of pairs of open charm hadrons in pp collisions at a centre-of-mass energy of 7 TeV has been reported in ref. [1].For all measured production cross-sections the inclusion of charge conjugate …

An angular analysis of Λ 0 b → J /ψΛ decays is performed using a data sample corresponding to 1.0 fb -1 collected in pp collisions at √ s = 7 TeV with the LHCb detector at the LHC.A parity violating asymmetry …

The prompt production of charmonium χ c and J /ψ states is studied in proton-proton collisions at a centre-of-mass energy of √ s = 7 TeV at the Large Hadron Collider.The χ c and J /ψ mesons are identified through their decays …

The Bs0→J/ψKS0 branching fraction is measured in a data sample corresponding to 0.41fb−1 of integrated luminosity collected with the LHCb detector at the LHC. This channel is sensitive to the penguin contributions affecting the sin2β measurement from B0→J/ψKS0. The time-integrated branching fraction …
