dc.description.abstractAn amplitude analysis of the decay Λ b 0 → D 0 pπ - is performed in the part of the phase space containing resonances in the D 0 p channel. The study is based on a data sample corresponding to an integrated luminosity of 3.0 fb-1 of pp collisions recorded by the LHCb experiment. The spectrum of excited Λ c + states that decay into D 0 p is studied. The masses, widths and quantum numbers of the Λc(2880)+ and Λc(2940)+ resonances are measured. The constraints on the spin and parity for the Λc(2940)+ state are obtained for the first time. A near-threshold enhancement in the D 0 p amplitude is investigated and found to be consistent with a new resonance, denoted the Λc(2860)+, of spin 3 /2 and positive parity.
