TL;DR

This paper explores how tensor unparticles could significantly enhance gravitational interactions, potentially leading to black hole formation at TeV energies in high-energy collisions, without needing extra dimensions.

Contribution

It introduces a mechanism where unparticles modify gravity, enabling black hole production at collider energies, a novel alternative to extra-dimensional models.

Findings

Horizon radius increases to electroweak scale for TeV-mass black holes

Geometric cross-section for black hole production can reach up to 50 pb

Unparticle physics can facilitate black hole formation without extra dimensions

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.
