A COSMIC RAY SUPER HIGH ENERGY MULTIJET FAMILY EVENT

  • A cosmic ray super high energy family event with visible energy of about 1500TeV and five big cores is reported. This event was found in the 1980—1981 exposure of Mt. Kambala(5500M a.s.l.) emulsion chamber experiment. The family characteristics are analized and compared with the other cosmic ray events in the same energy range. The production and fragmentation characteristics of the five jets are studied and compared with the experimntal results of accelerators and C-jets as well as with QCD predictions up to TeV. Some features on hadronic interactions at TeV range are disccused.

A COSMIC RAY SUPER HIGH ENERGY MULTIJET FAMILY EVENT

    Corresponding author: ZOU Bao-Tang,

Abstract: A cosmic ray super high energy family event with visible energy of about 1500TeV and five big cores is reported. This event was found in the 1980—1981 exposure of Mt. Kambala(5500M a.s.l.) emulsion chamber experiment. The family characteristics are analized and compared with the other cosmic ray events in the same energy range. The production and fragmentation characteristics of the five jets are studied and compared with the experimntal results of accelerators and C-jets as well as with QCD predictions up to TeV. Some features on hadronic interactions at TeV range are disccused.
