英文摘要	The new measurements of production fractions of P-c states by LHCb collaboration have put restrictions on their branching ratios of J/psi p decay, thus constraining their photoproduction in gamma p -> J/psi p reaction. We show the tension between LHCb results and the current experiments in search of P, photoproduction. We also find that the present information of branching ratios of P-c -> J/psi p has already confronted sharply with the models which study the nature of P-c.
