Résumé

Les facteurs de forme physiques d’une particule de spinJ sont définis de façon, covariante en utilisant une représentation d’hélicité du courant électromagnetique dans le système de Breit. La forme générale de la section efficace non polarisée est donnée explicitement. La matrice densité est calculée dans le cas d’un spin J=3/2.

Riassunto

Si definiscono in modo covariante i fattori di forma fisici di una particella di spinJ, utilizzando una rappresentazione d’elicità della corrente elettromagnetica nel sistema di Breit. Si da esplicitamente la forma generate della sezione d’urto non polarizzata. Si oalcola la matrice di densità nel caso di spinJ = 3/2.
