Chiral aspects of hadron structure

Abstract

Chiral loop corrections for hadronic properties are considered in a constituent quark model. It is emphasized that the correct implementation of such corrections requires a sum over intermediate hadronic states. The leading non-analytic corrections are very important for baryon magnetic moments and explain the failure of the sum rule $({\mu }_{{\Sigma }^{+}}+2{\mu }_{{\Sigma }^{-}})/{\mu }_{\Lambda }=-1$ predicted by the constituent quark model.
