| 英文摘要 | An amplitude analysis of the decay lambda(0)(b) -> d(0)p pi(-) 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 lambda(+)(c) states that decay into d(0)p is studied. the masses, widths and quantum numbers of the lambda(c)(2880)(+) and lambda(c) (2940)(+) resonances are measured. the constraints on the spin and parity for the lambda(c)(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 lambda(c) (2860)(+), of spin 3/2 and positive parity. |
