N2 - The search for supersymmetric partners at Large Hadron Collider revealed negative result. Though, strictly speaking, it does not exclude low energy supersymmetry, but still it leads to strong constraints of the parameter space. Therefore the search for supersymmetric particles at higher energies becomes of interest. It is shown that in R2-modified cosmology heavy particles with the interaction strength typical for supersymmetry could be promising candidates for carriers of dark matter. We consider the heating of the Universe at the postinflationary stage via particle production by oscillating curvature scalar (scalaron). The bounds on the masses of dark matter particles are obtained for different dominant decay modes of the scalaron. Possible impact of superheavy particle decays on the spectrum of ultra high energy cosmic rays (UHECR) is discussed.
