Abstract
It is well known that some black holes can act as accelerators for particles without spin. Recently, some works have considered the collision of two spinning particles in the background of Schwarzschild and Kerr black holes and it has been shown that the center-of-mass energy of the test particles is related to the spin. In this paper we extend the results to some more general cases. We consider Kerr-Newman black holes as accelerators for spinning particles. We derive the center-of-mass energy of the spinning particles and use numerical method to investigate how the center-of-mass energy is affected by the properties of the black holes and spinning particles.
