Subleading Heavy Quark Effects in a Nonrelativistic Quark Model
James F. Amundson
Abstract
I present a very simple model, based on the model of Isgur, Scora, Grinstein and Wise ISGW, which can be used to calculate the effects which appear at subleading order in heavy quark effective theory. I include both general formalism and specific results. The formalism transparently reproduces the results of heavy quark effective theory, while giving insight into such things as the vanishing of certain form factors at zero recoil. I discuss the implications of these results for both heavy quark effective theory and the Isgur-Scora-Grinstein-Wise model.
