چکیده
It is shown that an instanton induced interaction between quarks produces a very deeply bound H-dibaryon with mass below 2M N , M H = 1718 MeV. Therefore the H-dibaryon is predicted to be a stable particle. The reaction of photodisintegration of H-dibaryon to 2Λ in during of its penetration into cosmic microwave background will result in a new possible cutoff in the cosmic-ray spectrum. This provides an explanation of ultra-high energy cosmic ray events observed above the GZK cutoff as a result of the strong interaction of high energy H-dibaryons from cosmic rays with nuclei in Earth's atmosphere.

The MACRO detector is located in the Gran Sasso Laboratory. MACRO's overburden varies from 3150 to 7000 hg/cm 2. A transition radiation detector (TRD) has been added to the MACRO detector in order to measure the residual energy of muons entering MACRO, i.e. the energy they have after passing through the Gran Sasso's rock overburden. The TRD consists of three identical modules with a total horiz...

We analyze the spectrum of the ultrahigh energy (above ≈ 10 9 GeV) cosmic rays. With a maximum likelihood analysis we show that the observed spectrum is consistent with the decay of extragalactic GUT scale particles. The predicted mass for these superheavy particles is m X = 10 b GeV, where b = 14.6
