Summary
In a particular case, we show how to determine exactly hadronic production cross-sections σ n (s) satisfying general phenomenological constraints such as the asymptotic proportionality of <n> and σ in and the empirical rule obeyed by the dispersion. KNO scaling is automatically a property of σ n . Whereas the predictions for higher moments do not compare unfavourably with the data, they suggest that the method can be improved.
Riassunto
Si mostra come, in un caso particolare, le sezioni d'urto adroniche di produzione σ n (s) possano essere determinate in modo che siano automaticamente soddisfatti vincoli fenomenologici di tipo generale, come per esempio la proporzionalità asintotica di <n> e di σ n e la legge empirica per la dispersione. L'invarianza di scala di KNO risulta essere una proprietà automatica per le σ n . Mentre le predizioni che si ottengono per i momenti più elevati sono ragionevolmente buone, indicano ciò nonostante che il metodo può essere migliorato rendendolo più generale.
Резюме
В специальном случае мы показываем, как определить точно поперечные сечения рождения адронов σ n (s), удовлетворяющие общим феноменологическим ограничениям, таким как асимптотичесиая пропорциональность <n> и σ n и эмпирическое правило, связанное с дисперсией. KNO скейлинг представляет автоматически свойство σ n . Предсказания для высших моментов не соответствуют данным, поэтому предложенная модель может быть улучшена.
