The spectrum of ultrahigh energy (above approximate to 10(9) GeV) cosmic rays is consistent with the decay of grand unification scale particles. The predicted mass is m(x) = 10(h) GeV, where h = 14.6(-1.7)(+1.6).

The QCD equation of state at finite baryon density is studied in the framework of a Cluster Expansion Model (CEM), which is based on the fugacity expansion of the net baryon density. The CEM uses the two leading Fourier ...

We show that all features of the ultrahigh energy cosmic ray spectrum from 10^{17} eV to 10^{21} eV can be described with a simple power-like injection spectrum of protons under the assumption that the neutrino-nucleon ...
