Abstract

At present, production, properties, and decays of heavy baryons are vigorously studied both experimentally and theoretically. The \(SU(3)_{F}\) flavor symmetry allows an existence of a large number of hidden charm pentaquark states which differ by their light quark content. Here, ratios of weak decay widths of bottom baryons into a pentaquark and light meson are presented. The most interesting for experimental observation decays of bottom baryons are specified.

Notes

  1. Pentaquark states \(P_{c}\) decaying into the proton and \(J/\psi\)-meson are suggested to denote according to the exotic hadron naming convention [2] as \(P_{\psi}^{N+}\).

  2. This state decaying into the \(\Lambda\)-hyperon and \(J/\psi\)-meson according to [2] is called as \(P_{\psi s}^{\Lambda 0}\).
