High-energy proton-proton collision by a solvable model

  • Published:
Il Nuovo Cimento A (1965-1970)

Summary

The reactions induced by high-energy proton-proton collisions are analysed in terms of a theoretical model, which incorporates exacts-channel unitarity. A unified description of the salient aspects of high-energy proton-proton interactions is obtained. Among those aspects we choose for more detailed analysis: the total cross-section, the multiplicity, the distribution of the number of the emitted particles, the elastic cross-sections and, with particular attention, the inclusive reactions p + p → π + anything and p + p → p + anything. A comparison with the experimental data is presented and the general agreement turns out to be satisfactory.

Riassunto

Si analizzano reazioni indotte dall’urto tra due protoni ad alta energia tramite un modello teorico, che soddisfa esattamente alle condizioni d’unitarietà nel canale diretto. Si ottiene così una descrizione unificata degli aspetti salienti dell’interazione ad alta energia fra due protoni. Tra questi aspetti si scelgono per un’analisi più dettagliata la sezione d’urto totale, la molteplicità, la distribuzione del numero di particelle emesse, la sezione d’urto elastica e, con particolare attenzione, le reazioni inclusive p + p → π + + resto e p + p → p + resto. Si confrontano le previsioni teoriche con i dati sperimentali e l’accordo generale risulta soddisfaciente.
