Ultrahigh energy head-on collisions without horizons or naked singularities: General approach
Ultrahigh energy head-on collisions without horizons or naked singularities: General approach
Recently, alternatives to the Ba\~nados, Silk, and West effect were proposed which are (i) due to the existence of naked singularities instead of the horizon and (ii) require neither horizon nor naked singularity. We reveal the main features of such alternatives in a model-independent way. The metric should be close …
