Summary
Form factors analogous toF c andF M in nucleon electromagnetic interactions are suggested for the vector and axial-vector currents at the strong vertex in a current-current theory of weak interactions. They are used to compute the cross-section and expressions for the covariant polarization four-vectors for the two final particles in the process v(v) + N → l + b with a view to determining the form factors and testing time-reversal invariance.
Riassunto
Fattori di forma analoghi aF c eF m nelle interazioni elettromagnetiche fra nuolconi vengono suggeriti per le correnti vetteriali e di vettori assiali nel vertice forte in una teoria « oorrente-oorrente » delle interazioni deboli. Essi vengono usati per calcolare la sezione d’urto e le espressioni dei quadrivettori covarianti di polarizzazione per le due particelle fmali nel prooesso v(v) + N → l + b allo scopo di determinare i fattori di forma e provare l’invarianza rispetto all’ inversione del tempo.
