On observed and predicted multiplicities in very-high-energy interactions

  • P. K. F. Grieder
Article

Summary

Recent hydrogen bubble chamber and hydrogen target multiplicity data are compared with the bulk of existing data over the entire experimental energy range, from 10 to 108 GeV. The data are compared with multiplicity predictions, derived from different interaction models. Included in the analysis are also results obtained from recent large-scale air shower simulations, in conjunction with experimental air shower data. Multiplicity tendencies of very-high-energy nucleon-nucleus interactions, as observed in emulsion and derived from air shower simulations, are discussed in view of the recent HBC and hydrogen target data.

О наблюдаемых и предскаэанных множественностях в вэаимодействиях при очень высоких знергиях

Реэюме

Данные по множественности, полученные недавно на водородной пуэырьковой камере и водородной мищени, сравниваются с массой сушествуюших данных, которые покрывают всю зкспериментальную область знергий от 10 до 108 ГзВ. Эти данные сравниваются с предскаэаниями множественности, полученными иэ раэличных моделей вэаимодействий. Включенные в аналиэ данные также получены иэ последних моделирований атмосферных ливней больщого масщтаба и иэ зкспериментальных данных по атмосферным ливням. В свете последних данных на водородной пуэырьковой камере и водородной мищени обсуждаются тенденции множественностей в нуклон-ядерных вэаимодействиях при очень высоких знергиях, которые наблюдаются в змульсии и выводятся иэ моделирований атмосферных ливней.

Riassunto

Si confrontano i recenti dati delle molteplicità delle camere a bolle a idrogeno e dei bersagli di idrogeno con la maggior parte dei dati esistenti sull’intero intervallo di energie sperimentali, da 10 a 108 GeV. Si confrontano i dati con le predizioni di molteplicità dedotte da differenti modelli di interazione. Si includono nell’analisi anche i risultati ottenuti in recenti simulazioni di sciami dell’aria di grande scala, in unione con i dati sperimentali sugli sciami dell’aria. In vista dei recenti dati delle camere a bolle a idrogeno e dei bersagli di idrogeno si discutono le tendenze di molteplicità delle interazioni nucleone-nucleo di altissima energia, come sono osservati nelle emulsioni e dedotte dalle simulazioni di sciami dell’aria.
