Summary
It has been shown that information on\(\bar p^4 He\) annihilation may impose limits on the possible amount of antimatter in the early Universe and other important cosmological parameters. We discuss which channels of\(\bar p^4 He\) annihilation must be measured and what restrictions on the parameters of GUT and SUSY models may be obtained from knowledge of the effective yields of different elements in\(\bar p^4 He\) annihilation.
Riassunto
Si mostra come le informazioni sul processo di annichilazione di antiprotoni in elio possano porre limiti sulla quantità possibile di antimateria all'origine dell'Universo e su altri importanti parametri cosmologici. Si discute quali canali dell'annichilazione\(\bar p^4 He\) possono essere misurati e quali limiti ai parametri dei modelli della GUT e SUSY possono essere ottenuti dalla conoscenza delle effettive probabilità di produzione dei diversi elementi dell'annichilazione\(\bar p^4 He\).
Резюме
Показывается, что информация о\(\bar p^4 He\) аннигиляции может накладывать ограничения на возможное количество антивещества в ранней Вселенной и на другие важные космологические параметры. Мы обсуждаем, какие каналы\(\bar p^4 He\) аннитиляции должны быть измерены и какие ограничения на параметры моделей GUT и SUSY могут быть получены из информации об эффективном выходе различных элементов в процессе\(\bar p^4 He\) аннитиляции.
