Acceleration of particles by rotating acceleration horizons    [PDF]

O. B. Zaslavskii

We consider collision of two particles in the vicinity of the extremal acceleration horizon that includes the extremal Ker throat. It is shown that the energy in the centre of mass frame can become indefinitely large if parameters of one of particles are fine-tuned (so-called critical particle). Thus the Ba\~nados-Silk-West (BSW) effect is possible in such space-times contrary to some recent claims in literature. As the vicinity of the extremal black hole horizon can be approximated by the metric of the acceleration one, this also gives the bridge between two kinds of the BSW effect.
