| English Abstract | A full amplitude analysis of lambda(0)(b) -> j/psi pi(-) decays is performed with a data sample acquired with the lhcb detector from 7 and 8 tev pp collisions, corresponding to an integrated luminosity of 3 fb(-1). a significantly better description of the data is achieved when, in addition to the previously observed nucleon excitations n -> p pi(-), either the p-c(43800)(+) and p-c(4450)(+) -> j/psi p states, previously observed in lambda(0)(b) -> j/psi pk(-) decays, or the z(c)(4200)(-) -> j/psi pi(-) state, previously reported in b-0 -> j/psi k+pi(-) decays, or all three, are included in the amplitude models. the data support a model containing all three exotic states, with a significance of more than three standard deviations. within uncertainties, the data are consistent with the p-c(4380)(+) and p-c(4 450)(+) production rates expected from their previous observation taking account of cabibbo suppression. |
