【 摘 要 】

Dyson-Schwinger equations provide an effective approach to physics of stronginteractions. To reproduce the hadronic phenomenology well, the Dyson-Schwinger approachin the rainbow-ladder approximation must employ an effective interaction between quarkswhich is fairly strong at intermediate (Q² ~ 0.5 GeV²)spacelike transferred momenta. We have recently proposed that such an interaction mayoriginate from the dimension-2 gluon condensate
