Rotating AyónBeatoGarcía black hole as a particle accelerator
Abstract
We study the collision of two particles with equal masses moving in the equatorial plane near the horizon of the rotating regular AyónBeatoGarcía (ABG) black hole (BH) and calculate the centerofmass (CM) energy for the colliding particles for both extremal and nonextremal cases. It turns out that CM energy depends not only on rotation parameter a but also on charge Q . Particularly for the extremal rotating regular ABG BH, the CM energy of two colliding particles could be arbitrarily high for the critical angular momentum of particles. Furthermore, we also show that, for a nonextremal BH, there exists a finite upper limit of CM energy, which changes with charge Q . A comparison with Kerr and KerrNewman black holes is included.
