The Super-Heat-Kernel Expansion and the Renormalization of the Pion-Nucleon Interaction
A recently proposed super-heat-kernel technique is applied to heavy baryon chiral perturbation theory with two flavours. A previous result for the one-loop divergences of the pion-nucleon system is confirmed, giving at the same time an impressive demonstration of the efficiency of the new method. Th...
