The transverse-momentum distribution in the central region in a phenomenological dual model

Распределение поперечного импульса в центральной области в феноменолигической дуальной модели

Summary

A phenomenological dual amplitude for double pomeron exchange is evaluated for the transverse-momentum distribution atx=0. It shows an exp [−bp ] dependence for lowp values and a subsequent flattening-off for largerp . The results are compared with ISR data. Some analogies to the statistical bootstrap model are discussed.

Riassunto

Si valuta un’ampiezza duale per lo scambio doppio del pomerone per la distribuzione dell’impuso trasversale adx 2=0. Essa presenta una dipendenza da exp [−bp ] per piccoli valori dip ed un successivo appiattimento per maggiorip . Si confrontano i risultati con i dati degli ISR. Si discutono alcune analogie con il modello di bootstrap statistico.

Реэюме

Вычисляется феноменологическая дуальная амплитуда для распре-деления поперечного импульса приx=0. Попучается эависимость ехр [−bp ] для малых величинp (p ⩽1 ГзB/c) и последуюшее сглаживание для больщих эна-ченийp . Этот реэультат сравнивается с зкспериментами на встречных накопи-тельных кольцах. Обсуждаются некоторые аналогии со статистической моделью бутстрапа.
