Abstract

We introduce analytical quantum gravity modifications of the production cross section for terascale black holes by employing an effective ultraviolet cutoff 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 that the heretofore 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. Contrary to the classical black-disk result, our cross section is able to explain why black holes might not be observable in LHC experiments while they could be still within the reach of ultra-high-energy cosmic ray events.
