Transplanckian radiation in theories with extra dimensions

TL;DR

This paper investigates whether particles in high-energy collisions within TeV-scale gravity models can lose all their energy through bremsstrahlung when impact parameters are larger than the black hole's gravitational radius.

Contribution

It analyzes the energy depletion via bremsstrahlung in transplanckian collisions, providing insights into energy loss mechanisms in theories with extra dimensions.

Findings

Particles can significantly lose energy through bremsstrahlung at large impact parameters.

Energy depletion depends on impact parameter and gravitational radius.

Implications for black hole formation in TeV-scale gravity scenarios.

Abstract

We discuss whether the particles undergoing transplanckian collisions in TeV-scale gravity can deplete all their energy on bremsstrahlung for the impact parameters much larger than the gravitational radius of the presumably created black hole.
