title = "Observation of Λb0 → D + pπ− π− and Λb0 → D *+ pπ− π− decays",
abstract = "The multihadron decays Λb0 → D+pπ−π− and Λb0 → D*+pπ−π− are observed in data corresponding to an integrated luminosity of 3 fb−1, collected in proton-proton collisions at centre-of-mass energies of 7 and 8 TeV by the LHCb detector. Using the decay Λb0 → Λc+π+π−π− as a normalisation channel, the ratio of branching fractions is measured to beB(Λb0→D+pπ−π−)B(Λb0→Λc0π+π−π−)×B(D+→K−π+π+)B(Λc0→pK−π−)=(5.35±0.21±0.16)%, where the first uncertainty is statistical and the second systematic. The ratio of branching fractions for the Λb0 → D*+pπ−π− and Λb0 → D+pπ−π− decays is found to beB(Λb0→D∗+pπ−π−)B(Λb0→D+pπ−π−)×(B(D∗+→D+π0)+B(D∗+→D+γ))=(61.3±4.3±4.0)%.",
