High-energy behaviour of feynman integrals involving singular configurations

  • Published:
Il Nuovo Cimento (1955-1965)

Summary

The high-energy asymptotic behaviour of Feynman diagrams containing certain singular configurations is investigated. The leading contributions are factorized and summed to give Regge-pole terms. A new feature of the discussion is that it is sometimes necessary to scale disconnected sets of lines in addition to the usual connected sets.

Riassunto

Si studia il comportamento asintotico alle alte energie dei diagrammi di Feynman contenenti alcune configurazioni singolari. Si fattorizzano e si sommano i contributi principali in modo da dare i termini dei poli di Regge. Una nuova caratteristica della discussione sta nel fatto che talvolta è necessario bilanciare gruppi di linee non connessi oltre ai soliti gruppi connessi.
