The centre-of-mass energy of two colliding particles in STU black holes

Hassan Saadat

Abstract

In this paper we consider the collision of two particles near an STU black hole and calculate the centre-of-mass energy. In the case of an uncharged black hole we find that the maximum energy occurs near the black hole horizon, similar to the case of a charged black hole. We confirm that black hole charge decreases the centre-of-mass energy near the black hole horizon.
