Ultrahigh Energy Cosmic Rays

At the present moment, there is an unresolved problem in the physics of cosmic rays. The problem concerns the origin of the ultrahigh energy cosmic rays. One of the possible mechanisms of the particle’s birth with such energy is bound to the processes occurring in the active nuclei of the galaxies. In this paper, we have examined a collision of superheavy particles. Using the Weinberg formalism, we have estimated gravitational radiation emitted during the collision in the first approximation. It was shown that, for a certain collision time, the energy lost by the ultrarelativistic particle is less than the value of the energy of the mass center of the collision and the mass of the colliding particles.
