Planckian Scattering and Shock Wave Mixing in General Relativity and Dilaton Gravity

TL;DR

This paper surveys high-energy point particle scattering at Planckian energies, focusing on electromagnetic and gravitational interactions, and explores shock wave mixing in Einsteinian and dilatonic gravity frameworks.

Contribution

It introduces the analysis of shock wave interactions and mixing in both general relativity and string-inspired dilaton gravity at Planckian energies.

Findings

Electromagnetic charge-monopole scattering exhibits novel features.

Shock wave mixing occurs due to combined electromagnetic and gravitational effects.

The study extends to dilatonic gravity, revealing new interaction phenomena.

Abstract

Point particle scattering at Planckian centre-of-mass (cm) energies and low fixed momentum transfers, occurring due both to electromagnetic and gravitational interactions, is surveyed, with particular emphasis on the novel features occurring in electromagnetic charge-monopole scattering. The issue of possible mixing of the shock waves occurring due to both kinds of interactions is then addressed within the framework of Einsteinian general relativity and the dilatonic extension suggested by string theory.
