title = "Study of beauty hadron decays into Pairs of charm hadrons",
abstract = "First observations of the decays Λ0 b → Λc+D- (s) are reported using data corresponding to an integrated luminosity of 3 fb-1 collected at 7 and 8 TeV center-of-mass energies in proton-proton collisions with the LHCb detector. In addition, the most precise measurement of the branching fraction B(B0 s → D+D- s) is made and a search is performed for the decays B0 (s) → Λc +Λc -. The results obtained are (Equastion presented) Measurement of the mass of the Λ0 b baryon relative to the B¯0 meson gives M(Λ0 b) - M(B¯0) = 339.72±0.24(stat) ± 0.18(syst) MeV=c2. This result provides the most precise measurement of the mass of the Λb 0 baryon to date.",
