A parametrization of the transverse-momentum distribution in hadron collisions

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

Summary

We present an empirical parametrization of particle production data in hadron collisions whereby we account for the limited trasverse-momentum distribution of emitted particles (centered around 0.3 GeV/c) in terms of the uncertainty relation, Δx TΔp t≥ħ/2. By making a precise, consistent definition of the conjugate spatial co-ordinate, we are able (contrary to an earlier suggestion) to account for the dependence of the center in thep Tdistribution of incident momentum and type of projectile in close agreement with experiment.

Riassunto

Si presenta una parametrizzazione empirica dei dati relativi alla produzione di particelle in collisioni hadroniche per le quali si tiene conto della distribuzione limitata degli impulsi trasversi delle particelle emesse (centrati attorno a 0.3 GeV/c) in funzione della relazione di indeterminazione Δx TΔp T≥ħ/2. Fornendo una definizione precisa e consistente della coordinata spaziale coniugata, si può tener conto della dipendenza del centro della distribuzione dip Tdall'impulso incidente e dal tipo di proiettile, in buon accordo con gli esperimenti.
