Unimagined Imaginary Parts in Heavy Quark Effective Field Theory

Abstract

We argue that the imaginary parts of the anomalous dimensions in the multiparticle sectors of heavy quark effective field theory may be removed by a suitable redefinition of the multiparticle states. The connection between the imaginary parts of the anomalous dimensions and the interquark potential is pointed outComment: 14 Pages, LaTeX, HUTP-93/A009, IKDA 93/
