Abstract

We study the collision of two particles with equal masses moving in the equatorial plane near horizon of the rotating regular Ay\'on-Beato-Garc\'ia (ABG) black hole (BH) and calculate the center-of-mass (CM) energy for the colliding particles for both extremal and non-extremal cases. It turns out that CM energy depends not only on rotation parameter aa but also on charge QQ. Particularly for the extremal rotating regular ABG BH, CM energy of two colliding particles could be arbitrarily high for critical angular momentum of particles. Furthermore, we also show that, for a non-extremal BH, there exist a finite upper limit of CM energy, which changes with charge QQ. A comparison, with Kerr and Kerr-Newman black holes, is included.
