Strong damping of large momentum transfers, and its consequences for high-energy inelastic processes

  • S. C. Frautschi


High-energy inelastic processes are treated in a model which resembles the repeated one-pion exchange model, but with the (t - μ2 -1 dependence of pion exchange on momentum transfert replaced by a decreasing exponential dependence. The exponential dependence is motivated by, and assumed to be similar to, elastic proton-proton scattering results. The fireball emerges as a natural concept in this model, and results in qualitative agreement with many properties of cosmic-ray interactions are obtained. The model does not involve Regge poles explicitly, but some problems connected with Regge poles in inelastic processes are discussed in an Appendix.


Si trattano i processi anelastici di alta energia con un madello che somiglia al modello a scambio ripetuto di un pione, ma con la dipendenza secondo (t - μ2 -1 dello scambio dei pioni dal trasferimento dell’impulsot, sostituito da una dipendenza esponenziale decrescente. La dipendenza esponenziale è motivata dai risultati dello scattering elastico protone-protone, ed è supposta simile ad esso. La « fire-ball » emerge in questo modello come un concetto naturale, e si ottengono risultati qualitativamente in accordo con moite propriétá delle interazioni dei raggi cosmici. Il modello non coinvolge esplicitamente i poli di Eegge, ma nell’Appendice si discutono alcuni problemi connessi con i poli di Eegge nei processi anelastici.
