Summary
In a recent two-component fireball model applied to pp multiplicity data the central fireball was expressed as a convolution integral over a KNO extrapolation of\(p\bar p\) annihilation with a weight functionF(z). This analysis is extended here to π±p and K±p for machine energies above 10 GeV/c. Scaling functionsF(z) for each class of these processes are obtained and their similarity to that for pp interactions is noted. A single scaling function is capable of describing satisfactorily all the experiments treated independently of their energy and of the nature of the incoming hadrons.
Riassunto
In un recente modello a due componenti applicato ai dati di molteplicità pp il fireball centrale è stato espresso come un integrale di convoluzione su un’estrapolazione KNO dei dati di annichilazione\(\bar pp\) con funzione pesoF(z). Questa analisi è qui estesa ai processi π±p e K±p per energie sopra 10 GeV/c. Sono state ottenute delle funzioni di scalaF(z) per ciascun tipo di processo ed è stata notata la somiglianza con quella ottenuta pei le interazioni pp. Una singola funzione di scala è capace di descrivere soddisfacentemente tutti gli esperimenti trattati indipendentemente dalla loro energia e dalla natura degli adroni incidenti.
