Reliable Perturbative Results for Strong Interactions?

Phys. Rev. Lett. 30, 1346 – Published 25 June 1973
H. David Politzer


An explicit calculation shows perturbation theory to be arbitrarily good for the deep Euclidean Green's functions of any Yang-Mills theory and of many Yang-Mills theories with fermions. Under the hypothesis that spontaneous symmetry breakdown is of dynamical origin, these symmetric Green's functions are the asymptotic forms of the physically significant spontaneously broken solution, whose coupling could be strong.
