Topic of Research Seminar: Center of Mass Energy of Particles Around Some Black Hole Spacetime

Abstract: His work aims to study the center of mass energy of the collision of particles around different black hole spacetimes. We study the dynamics of a charged particle in the vicinity of magnetic Schwarzschild, Reissner-Nordstr\”{o}m, Kerr and Kerr-Newman black holes in Boyer-Lindquist coordinates. Further, in Boyer-Lindquist coordinates, we elucidate the center of mass energy of two charged particles near the magnetic Schwarzschild, Reissner-Nordstr\”{o}m, Kerr and Kerr-Newman black holes. We find the dynamics and center of mass energy of two charged particles around the magnetic Schwarzschild and Reissner-Nordstr\”{o}m black holes using the non-singular coordinates. We check whether the center of mass energy near the outer horizon becomes infinite in non-singular coordinates or it is due to the singular nature of the Boyer-Lindquist coordinates. The center of mass energy can not be limited to the collision of two particles. We investigate the center of mass energy of three neutral particles around a Kerr-MOG black hole
