LHCb pentaquarks in constituent quark models

The Pc(4380)+ and Pc(4450)+ are studied as molecular states composed by charmed baryons and open charm mesons. Several bound states with the proper binding energy are found in the D¯Σc⁎ and D¯⁎Σc channels. We discuss the possible assignments of these states from their decay widths. Moreover, two more states are predicted, associated with the D¯Σc and D¯⁎Σc⁎ thresholds.
