Description

A production and decay model that incorporates theoretical and previously unrecognized experimental constraints on the LHCb pentaquark states is presented. The model satisfies all constraints and successfully fits the entire invariant mass distribution (unlike previous work). We find strong evidence for Sigma_c D molecular states along with threshold cusp and triangle singularities. Suggestions for future experiments will be made.
