Evidence for the fourth P_11 resonance predicted by the constituent quark model

It is pointed out that the third of five low-lying P_11 states predicted by a constituent quark model can be identified with the third of four states in a solution from a three-channel analysis by the Zagreb group. This is one of the so-called "missing" resonances, predicted at 1880 MeV. The fit of the Zagreb group to the piN -> niN data is the crudial element in finding this fourth resonance in the P_11 partial wave.
