The Lambdac(2940)+ baryon with possible quantum numbers J(P) = 1/2+ and 1/2- is studied as a molecular state composed of a nucleon and D* meson. We give predictions for the strong two-body decay channels Lambdac(2940)+ to p D0, Sigmac(++) pi(-) and Sigmac(0) pi(+) where the sum of partial widths is consistent with current data for the case of J(P) = 1/2(+). The case of J(P) = 1/2(-) is shown to be ruled out.

    A model calculation predicts fourteen double-heavy molecular pentaquark states, but their existence and binding energies depend critically on an unconstrained regularization parameter.

  2. Strong decays of the latest LHCb pentaquark candidates in hadronic molecule pictures

    hep-ph 2019-08 conditional novelty 4.0 of 10

    Treating Pc(4312), Pc(4440) and Pc(4457) as S-wave hadronic molecules, this paper computes decay widths and argues that spins 1/2^-, 1/2^- and 3/2^- respectively fit the measured widths.
