Gauge Theories in the Derivative Expansion
Abstract
Description
Gauge theories with and without matter are formulated in the derivative expansion. Amplitudues are derived as a power series in the energy scales; there are simplifications as compared with the usual loop expansion. The incorporation and summation of Wilson loops is natural in this approach and allows for a derivation of the confining potential as well as the masses of the gauge invariant observables.
