Threshold Two-Pion Photo- and Electroproduction: More neutrals than expected
V. Bernard, N. Kaiser, Ulf-G. Meißner +1
We present an exploratory study of two pion photo-- and electroproduction off the nucleon in the threshold region. To calculate the pertinent amplitudes, we make use of heavy baryo…

Aspects of Nucleon Compton Scattering
V. Bernard, N. Kaiser, Ulf-G. Meißner +1
We consider the spin-averaged nucleon forward Compton scattering amplitude in heavy baryon chiral perturbation theory including all terms to order . The chiral pred…

Consistent Calculation of the Nucleon Electromagnetic Polarizabilities in Chiral Perturbation Theory Beyond Next-to-Leading Order
Véronique Bernard, Norbert Kaiser, Armin Schmidt +1
We calculate the nucleons' electromagnetic polarizabilities in heavy baryon chiral perturbation theory including all terms to order . The chiral prediction of the e…
