N2 - We analyze the decay modes of the three [1212-]S=0,1 and [1232-]S=1 nonstrange pentaquarks with hidden charm and bottom, predicted by holographic QCD in the heavy quark limit. In leading order, the pentaquarks are degenerate and stable by heavy quark symmetry. At next to leading order, the spin interactions lift the degeneracy and cause the pentaquarks to decay. We show that the open charm (bottom) decay modes dwarf the hidden charm (bottom) ones, with total widths that are consistent with those recently reported by LHCb for charm pentaquarks. Predictions for bottom pentaquarks are given. The result of the current paper will be used in the part III of the current series of paper [18Y. Liu, K. A. Mamo, M. A. Nowak, and I. Zahed, following paper, Holographic charm and bottom pentaquarks. III. Excitations through photo-production of heavy mesons, Phys. Rev. D 104, 114023 (2021).PRVDAQ2470-001010.1103/PhysRevD.104.114023].
