We study the hadronic molecular structure of hidden heavy pentaquarks-new exotic states composed of charmed/bottom baryons and D(D*)/B(B*)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*) 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, gamma or P = eta(c), eta(b) mesons. Results are presented in the heavy quark limit.
