摘要：

We analyze the structure of QCD Green functions with one external nucleon, treated as a very massive field. We discuss the matching conditions and relations of various nucleon matrix elements of quark currents to the relativistic approach. Particular emphasis is put on the forward Compton amplitudes. Besides the nucleon electromagnetic polarizabilities we consider the spin-flip amplitude f2(omega2) to one-loop order. We predict the slope parameter of f2(omega2) which can be determined from the absorption cross sections of circularly polarized photons on polarized nucleons.
