Abstract

Presented here is a new method of applying perturbation theory to

e^{+} e^{-} \to hadrons

. Contact between theory and experiment is greatly enhanced by the introduction of a quantity that is both measurable and reliably calculable in perturbation theory. The method yields a value of approximately 700 MeV for

Λ

, the single parameter that characterizes the color-gluon force.
