Unparticle-Enhanced Black Holes at the LHC

Abstract

Based on the idea that tensor unparticles can enhance the gravitational interactions between standard model particles, potential black hole formation in high energy collisions is examined. Modifications to the horizon radius $r_H$ are derived, and the corresponding geometric cross-sections of such objects are calculated. It is shown that $r_H$ increases dramatically to the electroweak scale for masses $M_{BH} \sim 1-10 $TeV, yielding a geometric cross-section $\sigma_{BH}=\pi r_H^2$ on the order of $leq 50$ pb. This suggests that unparticle physics provides a mechanism for black hole formation in future accelerators, without the requirement of extra spatial dimensions.
