Angular correlations in the electroproduction of ρ-mesons

Угловые корреляции в злектророждении ρ-меэонов

  • Published:
Il Nuovo Cimento A (1971-1996)

Summary

Electroproduction of ρ-mesons followed by decay into two pions is studied. Angular correlations between the pions and electrons are explicitly evaluated. It is shown how a separation of the longitudinal and transverse photon cross-sections can be achieved. Distributions which allow a separation of the transverse and longitudinal photon cross-sections are emphasized.

Riassunto

Si studia l’elettroproduzione di mesoni ρ seguita dal decadimento in due pioni. Si valutano esplicitamente le correlazioni angolari fra i pioni e gli elettroni. Si mostra come si possa ottenere una separazione fra le sezioni d’urto longitudinale e trasversale del fotone. Si mettono in evidenza le distribuzioni che permettono una separazione delle sezioni d’urto trasversale e longitudinale del fotone.

Реэюме

Исследуется злектророждение ρ-меэонов с последуюшим распадом в два пиона. Аккуратно вычисляются угловые корреляции между пионами и злектронами. Покаэывается, как может быть достигнуто раэделение поперечных сеченй для продольных и поперечных фотонов. Осебое эначение придается распределениям, которые поэволяют раэделить поперечные сечения для продольных и поперечных фотонов.

This review contains excerpts from data presented to this conference by the Cambridge Bubble Chamber Group and the ABBHHM Collaboration. The Figures shown on p. 212 and p. 213 show that ϱ1−1 /Hel and Re ϱ10 /Hel are small for photoproduction of ρ0-mesons, indicating that double- and single-helicity-flip amplitudes are small.
