Summary
Under the assumption that particle production proceeds via the production of fireballs decaying independently of their formation according to a function with approximate exponential shape, a study has been made concerning the question of how the experimental inclusive single-particle momentum spectra impose restrictions on the variation with the fireball rapidityη of both the production probability of a fireball and its decay properties. The results concerning the fireball decay are compared with the predictions of various statistical models of cluster decay.
Riassunto
Nell’ipotesi che la produzione di particelle avvenga tramite la produzione di fireball che decadono indipendentemente dalla loro formazione secondo una funzione con forma approssimativamente esponenziale, si è studiato come gli spettri inclusivi sperimentali dell’impulso della particella singola impongano restrizioni sulla variazione sia della probabilità di produzione di una fireball che delle sue proprietà di decadimento con la rapidità η della fireball. Si confrontano i risultati concernenti il decadimento della fireball con le predizioni di vari modelli statistici del decadimento degli ammassi.

In the TM corrections for the decay chain have been introduced only afterwards (ref. (3)).
Furthermore we should show that theT(η)-function obtained in our analysis is indeed the slope parameter at smallE. However the way we made the fits (7) guarantees this. Furthermore we note that the Planck spectrum used for historical reasons is connected with a Boltzmann spectrum for the regions 0.14 <E ┴ ≲ 0.5 GeV only via a slight parallel shift.
