Abstract

We consider the collision of two particles having distinct rest masses and orbiting near a Kerr-MOG black hole, and we further determine the center-of-mass energy (i.e., CME) associated with the particles. It is found that the CME energy is influenced not only by the rotation parameter a, but also by the MOG parameter \(\alpha\). Notably, it is shown that an extremal Kerr-MOG black hole case leads to surprisingly high the CME if and only if the parameter a satisfies the values given in the range \((0,\sqrt{1+\alpha })\) which diverges from that observed in Kerr-like black holes, thus highlighting the distinct characteristics of Kerr-MOG black holes. We present compelling evidence suggesting that Kerr-MOG black holes potentially act as significant generators for high-energy particles within the polar region.
