Interpreting the LHCb Pentaquark States


  • Prof. Eric SWANSON

Primary authors



Current interpretations of the novel Pc pentaquark states are reviewed and it is shown that all of them are in conflict with experimental evidence on photoproduction from Jefferson Lab and unpublished data on branching fractions from LHCb. A model that incorporates production and final state dynamics that is capable of describing the data will be presented.
