The extra high energy cosmic rays spectrum in view of the decay of proton at the Planck scale

Original · EN
The structure of the extra high energy cosmic rays spectrum in view of the decay of proton is considered. The time required for proton travel from the source to the earth defines the limiting energy of proton. Protons with the energies more than the limiting energy decay and do not give contribution in the EHECRs spectrum. It is assumed that proton decays at the Planck scale. Depending on the range of distances to the EHECRs sources, the range of the limiting energies of proton is determined. This allows one to explain the structure of the EHECRs spectrum.
