Abstract
We consider the spin-averaged nucleon forward Compton scattering ampli tude in heavy baryon chiral perturbation theory including all terms to order O(q4). The chiral prediction for the spin-averaged forward Comp ton scattering amplitude is in good agreement with the data for photon energies omega less-than-or-equal-to 110 MeV. We also evaluate the nu cleon electric and magnetic Compton polarizabilities to this order and discuss the uncertainties of the various counter terms entering the c hiral expansion of these quantities.
