摘要：
We investigate the properties of mesons with the exotic J(PC) = 1(-+) quantum numbers. Starting out from the light-quark domain, where the pi(1) states are used as references, we predict the masses of analogous quarkonia for c (c) over bar and b (b) over bar configurations. We employ a covariant Dyson-Schwinger-Bethe-Salpeter-equation approach with a rainbow-ladder truncated model of quantum chromodynamics.
