Abstract
Pion and kaon observables are calculated using a Dyson-Schwinger Bethe -Salpeter formalism, It is shown that an infrared finite gluon propaga tor can lead to quark confinement via generation of complex mass poles in quark propagators. Observables, including electromagnetic form fac tors, are calculated entirely in Euclidean metric for spacelike values of bound state momentum and final results are extrapolated to the phy sical region, (C) 1998 Elsevier Science B.V.
