Unparticle-enhanced black holes at the LHC

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 rHrH are derived, and the corresponding geometric cross-sections of such objects are calculated. It is shown that rHrH increases dramatically to the electroweak scale for masses MBH∼1–10 TeVMBH∼1–10 TeV, yielding a geometric cross-section σBH=πrH2 on the order of ⩽50 pb⩽50 pb. This suggests that unparticle physics provides a mechanism for black hole formation in future accelerators, without the requirement of extra spatial dimensions.
