The poisson distribution of secondary particles in straight-line paths. Approximation in quantum field theory

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

Summary

The problem of multiple production of «soft» mesons in high-energy two-nucleon collision is considered in the framework of standard quantum field theory models. The straight-line-path approximation is used to obtain the Poisson distribution of the secondary-particle number and to investigate the average particle number as a function of the choice of the cut-off parameters for momenta of the secondary particles in various asymptotic regions.

Riassunto

Nel contesto dei modelli di teoria dei campi quantistici convenzionali si studia il problema della produzione multipla di mesoni «molli» nelle collisioni di due nucleoni di alta energia. Si usa l’approssimazione dei percorsi rettilinei per ottenere la distribuzione poissoniana del numero di particelle secondarie e per ricercare il numero medio di particelle in funzione della scelta dei parametri di taglio per gli impulsi delle particelle secondarie nelle varie regioni asintotiche.
