Confronting pentaquark photoproduction with new LHCb observations
The new measurements of production fractions of Pc states by LHCb collaboration have put restrictions on their branching ratios of J/ψp decay, thus constraining their photoproduction in γp→J/ψp reaction. We show the tension between LHCb results and the current experiments in search of Pc photoproduc...

| description | The new measurements of production fractions of Pc states by LHCb collaboration have put restrictions on their branching ratios of J/ψp decay, thus constraining their photoproduction in γp→J/ψp reaction. We show the tension between LHCb results and the current experiments in search of Pc photoproduction. We also find that the present information of branching ratios of Pc→J/ψp has already confronted sharply with the models which study the nature of Pc. |

We show the tension between LHCb results and the current experiments in search of $P_c$ photoproduction. We also find that the present information of branching ratios of $P_c\to J/\psi p$ has already confronted sharply with the models which study the nature of $P_c$.arXiv:1904.06015oai:cds.cern.ch:27592452019-04-11 |
