Description

Neutral pion photoproduction off the proton in the threshold region allows for fine tests of the QCD chiral dynamics. In this talk, I review the theoretical and experimental experimental efforts to tackle this problem, which have led to a consistent picture. Quite differently, little is known about neutral pion photoproduction off the neutron and the extension to electroproduction requires further work on both the theoretical as well as the experimental side.
