Collisional Penrose process involving a charged particle in the vicinity of a Kerr Newman black hole

Abstract

From our earlier work, we found that the black hole charge quenches the efficiency of the collisional Penrose process when we considered a charged, maximally spinning black hole as the backround where the process will occur. In this work we would extend this to collisions that includes one of the particles carrying a charge. We found that for the case where the sub-critical particle carries the charge and that all are ingoing, a negative charge would increase the efficiency. While a positive charge would decrease it.
