Masses of J^PC =1^-+ exotic quarkonia in a Bethe-Salpeter-equation approach

T. Hilger, M. Gomez-Rocha, A. Krassnigg

We investigate the properties of mesons with the exotic J^PC = 1^-+ quantum numbers. Starting out from the light-quark domain, where the π_1 states are used as references, we predi…
