On the limiting energy of the collision of elementary particles close to horizon of the rotating black hole

TL;DR

This paper argues that the energy of particle collisions near a rotating black hole's horizon is fundamentally limited by gravitational radiation, preventing trans-Planckian energies despite potential black hole formation.

Contribution

It provides a theoretical analysis showing that gravitational radiation constrains collision energies near black holes, limiting the growth of energy in high-energy particle interactions.

Findings

Collision energy cannot exceed the Planck value due to gravitational radiation.

Comparison between gravitational and electromagnetic radiation near Kerr black holes.

Energy growth in particle scattering is limited even if black holes form at trans-Planckian energies.

Abstract

Arguments are given for the conclusion that the energy of collision of two ultrarelativistic elementary particles due to gravitational radiation cannot exceed the Planck value. Comparison of the gravitational and electromagnetic radiation for charged particles close to the horizon of Kerr black hole is made. If for trans-Planckian energy the black hole can arise it is shown that the energy growth used in scattering for interaction of particles is still limited.
