Tests on helicity conservation in interactions π+p at 11.7 GeV/c and π−p at 11.2 GeV/c

Проверка сохранения спиралъности в вэаимодействиях π+p при 11.7 Гэв/с и π−p при 11.2 Гэв/с

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

Summary

Various diffractionlike reactions, selected from 11.7 GeV/c π+p and 11.2 GeV/c π−p interactions in the 1.5 m BNHBC and 2 m CERN-HBC are tested fors- andt-channel helicity conservation. From a detailed analysis of azimuthal distributions, no evidence is found either fors- ort-channel helicity conservation.

Riassunto

Si verifica la conservazione dell’elicità nei canalis et per diverse reazioni di tipo diffrattivo selezionate da interazioni π+p a 11.7 GeV/c e π−p a 11.2 GeV/c nelle camere a bolle da 1.5 m (BNHBC) e da 2 m (CERN-HBC). Da una analisi dettagliata delle distribuzioni azimutali non si trovano prove di conservazione dell’elicità né nel canales né nel canalet.

Реэюме

Исследуются раэличные дифракционно-под обные реакции, отобранные иэ вэаимодействий π+р при 11.7 ГзВ/с и π~р при 11.2 ГзВ/с в 1.5 м BNHBC и 2 м водородной пуэырьковой камере в ЦЕРНе, с целью проверки сохранения спиральности вs иt каналах. Иэ подробного аналиэа аэимутальных распределений не получено подтверждений сохранения спиральности ни дляs, ни дляt каналов.
