Abstract
The electroproduction of neutral pions off protons close to threshold is studied within the framework of chiral perturbation theory. We compare to the recent data from NIKHEF and find good agreement. Further measurements as tests of chiral symmetry are discussed.This publication has 21 references indexed in Scilit:
