Compositeness of Hadron Resonances and Quasi-Bound States

High Energy Physics - Phenomenology 2015-12-11 v1 Nuclear Theory

Abstract

We discuss the composite nature of hadrons appearing near the s-wave two-hadron threshold. Generalizing the Weinberg's weak-binding relation for stable bound states, we show that the compositeness of near-threshold resonances and quasi-bound states can be determined by observable quantities.
