 Masses for vector-1−−, axialvector-1+−, 1++, and exotic-vector 1−+ mesons are calculated within a quantum field theoretic framework based on the Dyson-Schwinger equations using a model form of the quark-antiquark interaction that is separable. The model provides an excellent description of π and K-meson observables and the flavor-octet ground-state meson spectrum. With no adjustments to model parameters, a numerical solution of the Bethe-Salpeter equation yields two exotic-1−+ mesons with masses of 1439 and 1498 MeV.
