Description
Singularities of Feynman amplitudes associated specifically with vanishing internal masses appear frequently in various applications of field theory. In examing the large momentum behaviour of Feynman amplitudes, we also encounter with such singularities since large momentum limit with fixed masses may be translated to certain zero mass limit with fixed momenta. It is the ultimate purpose to construct a general method for treating these so-called mass singularities. A brief account of the results obtained thus far is given here. (orig./BMS)
Abstract (German)
Singularitaeten von Feynman-Amplituden, die spezifisch mit verschwindend geringen inneren Massen assoziiert sind, tauchen in verschiedenen Anwendungen der Feldtheorie haeufig auf. Bei der Untersuchung des Verhaltens von Feynman-Amplituden bei hohen Impulsen finden sich ebenfalls derartige Singularitaeten, da grosse Impulsgrenzen bei festen Massen in Massen mit dem Grenzwert 0 bei festen Impulsen verwandelt werden kann. Endziel der Studie ist die Ausarbeitung einer allgemeinen Methode zur Behandlung dieser sogenannten Massensingularitaeten. Es wird ein kurzer Ueberblick ueber die bisher erzielten Ergebnisse gegeben.
