Abstract

Given a renormalization scheme of QCD, one can define a mass scale ΛQCD\Lambda_{\rm QCD} in terms of the beta function. Under a change of the renormalization scheme, however, ΛQCD\Lambda_{\rm QCD} changes by a multiplicative constant. We introduce a scheme independent ΛQCD\Lambda_{\rm QCD} using a connection on the space of the coupling constant.
