  • Published:
Il Nuovo Cimento A (1965-1970)

Summary

The methods and the techniques developed and used in a foregoing paper for the evaluation of the radiative corrections to the electron form factors up to fourth order in the electric charge (two internal loops) in QED are presented in this paper.

Riassunto

Si presentano in questo articolo i metodi e le tecniche sviluppati ed usati in un articolo precedente per il calcolo delle correzioni radiative ai fattori di forma dell’elettrone sino al quart’ordine nella carica elettrica secondo l’elettrodinamica quantica.

Реэюме

В зтой работе рассматриваются методы и техника, раэвитые и испольэованные в предыдушей статье для вычисления радиационных поправок к злектронным форм-факторам вплоть до четвертого порядка по злектрическому эаряду (две внутренние петли) в квантовой злектродинамике.

The derivation of the present work is given to unify as far as possible the treatment of all the three-body cuts.
