Structure singularities of electromagnetic form factors

  • Published:
Il Nuovo Cimento (1955-1965)

Summary

In local field theories the form factors of particles can have singularities which are characteristic for the structure of these particles as composite systems. These « structure singularities » are studied with the help of examples from perturbation theory. Their mathematical properties are described for real and complex values of the mass variable, and their physical implications are discussed.

Riassunto

Nelle teorie di campo locali i fattori di forma delle particelle possono presentare singolarità caratteristiche della struttura di tali particelle come sistemi composti. Si studiano queste « singolarità di struttura » con l’ausilio di esempi presi dalla teoria delle perturbazioni. Si descrivono le loro proprietà matematiche per valori reali e complessi della variabile di massa e se ne discute il significato fisico.

  7. The pion cloud of the nucleon must be folded into this long-range distribution; it changes the distribution, but does not affect the slope. One can easily draw corresponding Feynman diagrams, which then can be reduced, for the purpose of their analytic structure, to simpler graphs similar to that given in Fig. 1. See ref. (5),Y.
