Structure and decays of hidden heavy pentaquarks

Abstract

We study the hadronic molecular structure of hidden heavy pentaquarks - new exotic states composed of charmed/bottom baryons and $D(D^{\ast })/B(B^{\ast })$ mesons. Based on the observation of three pentaquark candidates $P_c^{+}(4312)$, $P_c^{+}(4440)$, and $P_c^{+}(4457)$ by the LHCb Collaboration we consider the classification of possible flavor partners composed of charmed baryons and $D(D^{\ast })$ mesons within the hadronic molecular approach. We extend this classification to the bottom sector. Using phenomenological Lagrangians we construct baryon-meson bound states governed by the Weinberg-Salam compositeness condition. As an application we consider strong two-body decays of the new exotic states into a light baryon and $V=J/\psi ,{\rm Y}$ or $P={\eta }_c,{\eta }_b$ mesons. Results are presented in the heavy quark limit.
