Azimuthal correlations in\(\bar pp\) interactions at 22.4 GeV/cinteractions at 22.4 GeV/c

Азимутальные корреляции в\(\bar pp\) взаимодействиях при 22.4 ГэВ/свзаимодействиях при 22.4 ГэВ/с

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

Summary

The inclusive azimuthal distributions of pion pairs are studies in\(\bar pp\) interactions at 22.4 GeV/c. The dependence of the asymmetry parameterB onn c, Δψ *, Δp *∥ and Δp ⊥ is studied. The influence of the ρ0 and Δ++ resonance production is estimated. The results show that neither the resonance production nor the Bose-Einstein symmetry effect suffice to explain the data.

Riassunto

Si studiano le distribuzioni azimutali inclusive di coppie di pioni nelle interazioni\(\bar pp\) a 22.4 GeV/c. Si studia la dipendenza del parametro di asimmetriaB dan c, Δy *, Δp * e Δp ⊥. Si valuta l’influenza di ρ0 e Δ++. I risultati mostrano che né la produzione di risonanza né l’effetto di simmetria di Bose-Einstein bastano per spiegare i dati.

Резюме

Изучаются инклюзивные азимутальные распределения пионных пар в\(\bar pp\) взаимодействиях при 22.4 ГэВ/с. Исследуется зависимость параметра асимметрииB отn c, Δy *, Δp *∥ и Δp ⊥. Оценивается влияние рождения резонансов ρ0 и Δ++. Полученные результаты указывают, что ни рождение резонансов, ни эффект симметрии Бозе-Эйнштейна не являются достаточными для объяснения экспериментальных данных.
