Unimagined Imaginary Parts in Heavy Quark Effective Field Theory

arXiv:hep-ph/9303224 · doi:10.1016/0370-2693(93)90301-W

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 out
