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