Study of Center of Mass Energy by Particles Collision in Some Black Holes

Abstract

This paper is devoted to the study of particles collision for two well-known black holes. We consider particles moving in equatorial plane and calculate their center of mass energy. Firstly, we explore center of mass energy of a regular black hole. In this case, acceleration and collision of particles lead to high center of mass energy which is independent of event horizon and naked singularity. Secondly, we investigate the center of mass energy of Plebanski and Demianski black hole (non-extremal) with zero NUT parameter. Here the center of mass energy depends upon the rotation parameter. We conclude that the center of mass energy becomes infinitely large for both black holes.
