TL;DR

This paper analyzes the collision energy of two particles near a Kerr-Newman-Taub-NUT black hole, showing that arbitrarily high energies are possible under certain conditions, with implications for black hole physics.

Contribution

It extends the analysis of collision energies to Kerr-Newman-Taub-NUT black holes, considering particles with different rest masses and specific parameters, including special cases.

Findings

High center of mass energy achievable near horizons

Conditions for arbitrarily high collision energies identified

Special case with identical particle parameters studied

Abstract

In this paper, we investigate the center of mass energy of the collision for two neutral particles with different rest masses falling freely from rest at infinity in the background of a Kerr-Newman-Taub-NUT black hole. Further, we discuss the center of mass energy near the horizon(s) of an extremal and non-extremal Kerr-Newman-Taub-NUT black hole and show that an arbitrarily high center of mass energy is achievable under some restrictions. We will study the special case of the center of mass energy when the specific energy, specific angular momentum and Carter constant of both the particles are same.
