Title: Any black holes at the LHC?

Authors: Jonas Mureika, Piero Nicolini, Euro Spallucci

Categories: hep-ph gr-qc hep-th

Comments: 10 pages, 1 figure

We introduce analytical quantum gravity modifications of the production cross

section for terascale black holes by employing an effective ultraviolet cut off

$l$. We find the new cross sections approach the usual "black disk" form at

high energy, while they differ significantly near the fundamental scale from

the standard increase with respect to $s$. We show here that the

discontinuous step function used to represent the cross section threshold can

realistically be modeled by two functions representing the incoming and final

parton states in a high energy collision. The growth of the cross section with

collision energy is thus a unique signature of $l$ and number of spatial

dimensions $d$. If these predictions prove to be model-independent, they

suggest black hole formation might be virtually impossible for collision

energies less than 100 TeV. While no such signals would be observed at the LHC,

attention should be focused on ultra-high energy cosmic ray events.
