Creation of superheavy particles in curved space-time and the dark matter problem.

The effect of creation of particles in nonstationary curved space-time leads to observable number of particles of the visible matter in the Universe for superheavy particles with the mass of the Grand Unification scale. The hypothesis of the decay of the short living component of these particles on quarks and leptons leads to ordinary matter while the longliving component survives up to modern time of the evolution of the Universe as dark matter.The possibility of explaining of Ultra High Energy Cosmic Rays Events (UHECR)as dark matter manifestations is discussed.
