Universal low energy features of two-body systems

Abstract

We apply renormalization ideas to study low-energy interactions in two-body systems. As we will see this method highlights a model-independent description of a broad variety of systems ranging from ultra-could atoms to NN and Lambda-Lambda interactions.Comment: 3 pages, 1 figure.
