Abstract:
We consider equatorial motion of test particles around a rotating Kerr
naked singularity in the Randall-Sundrum braneworld scenario and its
implications for the properties of Keplerian accretion disks. We
demonstrate existence of some unexpected phenomena related to properties
of spacetimes having positive braneworld tidal charges. This new
phenomenon can be an interesting explanation for extremely high energy
cosmic radiation.
