A formalism for parity-nonconserving reactions. — I

  • Published:

Summary

In this paper we develop a formalism for the analysis of a general parity-nonconserving reaction. The formalism is based on the introduction of parity-preserving and parity-changing helicity amplitudes. The partial-wave tmitarity relation and the crossing relations for general reactions are expressed in terms of the present formalism. The notion of maximal nonconservation of parity is discussed and the condition for it is obtained. Finally a simple example is worked out to illustrate the present formalism.

Riassunto

In questo articolo si sviluppa un formalismo per l’analisi di una reazione generica che non conserva la parità. Questo formalismo è basato sull’introduzione di ampiezze di elicità che conservano o cambiano la parità. Si esprimono, in base a questo formalismo, la relazione di unitarietá dell’onda parziale e le relazioni d’inerocio per reazioni generiche. Si discute la nozione di non massima conservazione della parità e se ne ottengono le condizioni. Infine si elabora un semplice esempio per illustrare il presente formalismo.
