Hidden-charm pentaquark states through current algebra: from their production to decay *

Abstract There may be seven hadronic molecular states. We construct their corresponding interpolating currents and calculate masses decay constants using QCD sum rules. Based on these results, we relative production rates in \Lambda_b^0 decays current algebra, that is, {\cal{B}}(\Lambda_b^0 \to P_c K^-):{\cal{B}}(\Lambda_b^0 P_c^\prime K^-) , where are two different also study properties via Fierz rearrangement further ratios the J/\psi p mass spectrum, K^- . Our results suggest D^{*} \Sigma_c^{*} states of J^P = 1/2^- 3/2^- observed future experiments.
