# Particle collisions on near horizon extremal Kerr background

@article{Galajinsky2013ParticleCO, title={Particle collisions on near horizon extremal Kerr background}, author={A. Galajinsky}, journal={Physical Review D}, year={2013}, volume={88}, pages={027505} }

Recently, Banados, Silk and West analyzed a collision of two particles near the horizon of the extremal Kerr black hole and demonstrated that the energy in the center-of-mass frame can be arbitrarily large provided the angular momentum of one of the colliding particles takes a special value. As is known, the vicinity of the extremal Kerr black hole horizon can be viewed as a complete vacuum spacetime in its own right. In this work, we consider a collision of two neutral particles within the… 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.
