Large-angle cross-sections p+p→A+B and π+p→A+B at high energies predicted by the statistical model

Summary

Large-angle cross-sections p+p→A+B and π+p→A+B are predicted using the statistical model. We formulate a condition for « central collisions » which, together with the relative probabilityP elastic/(ΣP)all channels, leads to a relation between the above large-angle cross-sections and the total inelastic cross-sections for pp and πp collisions. It is found that all these cross-sections, taken at c.m. scattering angles near to 90°, decrease exponentially with the total c.m. energy. For p+p→p+p a comparison with recent experiments shows good agreement over a range where this cross-section varies by five powers of ten.

Riassunto

Si prevedono le sezioni d’urto p+p→A+B e π+p→A+B per urti a grandi angoli servendosi del modello statistico. Poniamo per le « collisioni centrali » una condizione che, assieme alla probabilità relativaP el./(ΣP)tutti i canali, conduce a una relazione tra la suddette sezioni d’urto e la sezione d’urto anelastica totale per le collisioni pp e πp. Si è trovato che tutte queste sezioni d’urto prese ad angoli di scattering nel centro di massa prossimi a 90° decrescono esponenzialmente con l’energia totale nel centro di massa. Per la sezione p+p→p+p un confronto con recenti esperienze mostra buon accordo in un intervallo in cui la sezione d’urto varia di cinque potenze di dieci.
