Infra-red asymptotic forms of the gluon and quark propagators
Description
The infra-red asymptotic forms of the gluon and quark propagators are calculated using an approximation scheme to the Dyson-Schwinger equations, which was first developed in QED by Salam, Delbourgo and West. The power-law factor ( (lambda2/q2)sup(b) appears in the infra-red asymptotic form of the gluon propagator. This factor influences the infra-red asymptotic form of the quark propagator, which has the exponential damping factor exp[-2 Km2/+p2-m2+] at p2 asymptotically equals m2. (author)
