NN Interactions in QCD: Old and New Techniques
Abstract
Description
Since QCD is believed to be the underlying theory of the strong interaction, it is appropriate to study techniques that take into account more features of its rich and complex structure. We begin by discussing aspects of physics that are ill-reproduced by the usual one- or two-meson exchange approaches and identify the source of the deficiencies of these models. We then reveal promising methods for curing some of these ills, such as new quark potential models, baryon chiral perturbation theory, soluble strongly-interacting field theories, and large N_c QCD.
