Summary

We discuss a model for the description of high-energy collisions with nuclei in the frame of Glauber theoy in which the composite structure of nucleons is explicitly taken into account. A closed formula for the coherent cross-section is derived with simple assumptions about the scattering amplitude off a fundamental constituent (parton) and an intuitive nuclear wave function. The formula is shown to include well-known earlier results as limiting cases; its basic new features are pointed out.

Riassunto

Si discute un modello per descrivere urti ad alta energia su nuclei nell'ambito della teoria di Glauber tenendo conto della struttura composta dei nucleoni. Una formula esplicita per la sezione d'urto coerente è derivata sotto ipotesi molto semplificatrici sull'ampiezza d'urto per un costituente fondamentale (partone) e sulla funzione d'onda nucleare. Si dimostra che questa formula include risultati precedenti ben noti come casi limite; se ne mettono infine in evidenza le nuove caratteristiche principali.

Резюме

Мы обсуждаем модель для описания соударений адронов с ядрами при высоких энергиях в рамках теории Глаубера, в которой в явном виде учитывается составная структура нуклонов. Выводится замкнутая формула для когерентного поперечного сечения, испольэуя простые предположения об амплитуде рассеяния фундаментальных составляющих (партонов), и интутивную ядерную волновую функцию. Покаэывается, что полученная формула включает предыдущие хорошо известные результаты в предельных случаях. Отмечаются некоторье новые особенности этой формулы
