The chiral structure of the neutron as revealed in electron and photon scattering

Abstract

It is a consequence of QCD's spontaneously broken chiral symmetry that the response of the neutron to long wavelength probes will be driven by excitation of its pion cloud. In this article I discuss manifestations of this in electromagnetic form factors and Compton scattering. Particular attention is given to the interplay between this physics and shorter-distance components of the neutron's electromagnetic structure.
