Abstract We examine the possibility of arbitrarily high energy in the center-of-mass (CM) frame of colliding neutral particles in the vicinity of the horizon of a charged dilation black hole (BH). We show that it is possible to achieve the infinite energy in the background of the dilation black hole without fine-tuning of the angular momentum parameter. It is found that the CM energy ( E cm ) of collisions of particles near the infinite red-shift surface of the extreme dilation BHs are… Expand

It is shown that even under the most favorable idealized conditions the maximal energy of an escaping particle is only a modest factor above the total initial energy of the colliding particles, which implies that one should not expect collisions around a black hole to act as spectacular cosmic accelerators.
