Summary
The differential cross-sections for the processes π−p→(N*o)→l−l+n, where (3/2+, 3/2−, 5/2+, 7/2+) is any of the first four baryonic resonances (3/2+, 3/2−, 5/2+, 7/2+), have been calculated through a triple factorization procedure. The interest and difficulties of this type of experiment (in particular at the energy of the 7/2+ resonance) are discussed.
Riassunto
Si è calcolata, con un procedimento di tripla fattorizzazione, la sezione d'urto differenziale dei processi π−p→(N*o)→l−l+n, in cuiN* è una qualsiasi delle prime quattro risonanze barioniche (3/2+, 3/2−, 5/2+, 7/2+). Si discutono l'interesse e le difficoltà di questo tipo di esperimento (in particolare all'energia della risonanza 7/2+).
