The glory effect in pion-proton scattering

Глория-эффект в пион-протонном рассеянии

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

Summary

The backward peaks in positive pion-proton elastic scattering are interpreted as due to a glory effect, analogous to the optical glory, which explains the strong enhancement in the backward scattering of light by small water droplets. The mathematical formalism of the model is deduced through a Watson-Sommerfeld transform of the partial-wave expansion of the scattering amplitude.

Riassunto

I picchi a grandi angoli, nell'urto elastico pione-protone, sono descritti attraverso un effetto aureola, analogo a quello ottico; quest'ultimo spiega i picchi che si osservano a grandi angoli nella diffusione della luce da piccole gocce d'acqua. Il formalismo matematico della teoria è basato sulla trasformata di Watson-Sommerfeld dello sviluppo in onde parziali dell'ampiezza di diffusione.

Резюме

Пики в упругом рассеянии назад положительных пионов на протонах объясняются с помощью глория-эффекта, аналогичного оптической глории, которая объясняет сильное увеличение в рассеянии назад света на маленьких водяных каплях. Математический формализм этой модели выражается через преобразование Ватсона-Зоммерфельда для разложения амплитуды по парциальным волнам. Анализируется соответствие с экспериментальными данными.
