A new two-component model for pp topological gross-sections

Новая двухкомпонентная модель для pp топологическнх поперечных сечений

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

Summary

A new two-component picture of high-energy interactions is advanced. It consists of a three-fireball (inelastic) plus two-fireball (mainly elastic) structure. A somewhat simplified version is applied to pp multiplicities at machine energies. Very good fits are obtained, particularly if one excludes in the fitting procedure the occasional “erratic” data point. A comparison is made with a variant of the model which reduces to a conventional sum of two Poisson terms.

Riassunto

Si propone un nuovo modello a due componenti per le interazioni ad alta energia. La struttura del modello consiste di una componente (inelastica) a tre “fireball” più una componente (prevalentemente elastica), a due “fireball”. Una versione alquanto semplificata è applicata alle molteplicità per i processi pp a varie energie. I fit ottenuti sono molto buoni specialmente se sono esclusi nella procedura di calcolo alcuni punti da considerare “erratici”. Si fa anche un confronto con una variante del modello che si riduce ad una convenzionale somma di due Poisson.

Резюме

Предлагается новая двухкомпонентная картина взаимодействий при высоких знергиях. Зта картина включает трех-файрбольную (неупругую) плюс двух-файрбольную (в основном упругую) структуры. Для pp множественностей используется упрощенный вариант при ускорительных знергиях. Получается норощее соответствие, если в процедуре, подгонки используется метод случайных “блужданий”. Проводится сравнение с вариантом модели, которая сводится к обычной сумме двух пуассоновских членов.
