We consider collision of two particles in rotating spacetimes without horizons. If the metric coefficient responsible for rotation of spacetime is big enough, the energy of collisions in the center of mass frame can be as large as one likes. This can happen in the ergoregion only. The results are model-independent and apply both to relativistic stars and wormholes.

High Energy Collisions

We suggest two new scenarios of high-energy particle collisions in the background of a wormhole. In scenario 1, the novelty consists of the fact that the effect does not require two particles coming from different mouths. Instead, all such scenarios of high energy collisions develop, when an experimenter sends particles towards a wormhole from the same side of the throat. For static wormholes, this approach leads to indefinitely large energy in the center of mass. For rotating wormholes, it makes possible the super-Penrose process (unbounded energies measured at infinity). In scenario 2, one of colliding particles oscillates near the wormhole throat from the very beginning. In this sense, scenario 2 is intermediate between the standard one and scenario 1 since the particle under discussion does not come from infinity at all.

The One

In the framework of a systematic approach, the present status of the problem of instanton-like transitions in high energy particle collisions is reviewed. The arguments in favor of the exponential form of the total two-particle cross section in the one-instanton sector, exp [1/g2F(E/E sph )], are summarized. The perturbative technique for the evaluation of the function F(E/E sph ) is considered in detail. The nonperturbative semiclassical approach to the evaluation of F(E/E sph ), which may provide a reasonable basis for the numerical study of the problem, is discussed.
