Description
It is generally accepted that the sources of high-energy cosmic rays with energies below $10^{19}$ eV could be catastrophic astrophysical processes. However, the origin of the observed events with higher energies is not yet understood. We propose a mechanism for ultra-high-energy cosmic ray production through the decay and annihilation of superheavy dark matter particles. Such particles are naturally created in $R^2$-modified gravity via the decay of the scalaron.
