High energy particle collisions under Cauchy horizon
Abstract
We consider particle collision inside the inner horizon of the Reissner-Nordstrom metric in the so-called R region. We show that there exist scenario in which the enrgy in the center of mass frame grows unbounded. In contrast to the standard scenarios of high energy collisions in black hole background in the R region, fine tuning of particle parameters is not require. The effect found in this work can be considered as a massive particle counterpart of wave processes that contribute to instability of the inner black hole horizon.
