Two new mass relations for L=1 excited baryons Carlos Schat Ohio University and Universidad de Buenos Aires I will discuss how a quark model can be matched to the more systematic 1/Nc operator expansion for the masses of excited baryons. Assuming the most general two-body quark-quark interactions two new relations between the masses of L=1 baryons are found. These relations correlate their mixing angles and can be used to test for the presence of three-body forces.
