Low Energy Pion-Nucleus Interactions: Nuclear Deep Inelastic Scattering, Drell-Yan and Missing Pions
arXiv:nucl-th/9611043
Abstract
The experimental discovery that the nucleus is approximately transparent to low energy pions is reviewed. The consequences of this for nuclear deep inelastic scattering and Drell-Yan interactions are discussed. I argue that low energy nucleus data imply that there is little nuclear enhancement of the pion cloud of a nucleon, and try to interpret this in terms of nucleon-nucleon correlations.
