Description
We present a generic approach to the investigation of collisions of particles near black hole horizons. This takes into account that particles move in a generic axisymmetric spacetime (without specification of the metric functions) and that their motion is affected by the action of a force of unspecified nature. By requiring the horizon to be regular and forces to be finite, we obtain the set of conditions that have to hold to get the high energy of collision. Our algorithm allows to deduce whether the high-energy collision happens or not for various types of horizons and for various types of colliding particles. This analysis is required in the context of the consideration of black holes as particle accelerators.
