Unitarity constraints on a model for multiparticle production

Ограничения унитарности на модель для многочастичного рождения

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

Summary

The full two-body unitarity condition is applied to provide compatibility requirements constraining, in the high-energy, small-angle region, the parameters of a specific multiparticle production model. This model is very crude and over-simplified but the main purpose of the paper is to show the viability of a program in which the complete system of unitarity equations should be used in order to determine the form of the amplitude.

Riassunto

La condizione di unitarietà a due corpi (completa) è applicata allo scopo di studiare i vincoli da essa imposti nel limite di grandi energie e piccoli angoli sui parametri di uno specifico modello di produzione multipla. Questo modello è estremamente rozzo ma lo scopo del lavoro è di mostrare la fattibilità di un programma in cui il sistema completo di equazioni di unitarietà possa essere usato per determinare la forma od almeno le proprietà asintotiche delle ampiezze di produzione.

Реэюме

Условие полной двухчастичной унитарности испольэуется для того, чтобы удовлетворить требованиям, ограничиваюшим в области больщих знергий и малых углов параметры специфической модели многочастичного рождения. Эта модель является очень грубой и чреэмерно упрошенной, но главная цель статьи -покаэать жиэненность программы, в которой полная система унитарных уравнений должна быть испольэована для определения формы амплитуды.
