Renormalization and Universality of NN interactions in Chiral Quark and Soliton Models

Understand

We use renormalization as a tool to extract universal features of the NN interaction in quark and soliton nucleon models, having the same long distance behaviour but different short distance components.

• While fine tuning conditions in the models make difficult to fit NN data, the introduction of suitable renormalization conditions supresses the short distance sensitivity.
• Departures from universality are equivalent to extracting information on the model nucleon structure.
