Abstract
Based on the latest public results, 13 TeV data from the Large Hadron Collider at CERN has not indicated any evidence of hitherto tested models of quantum black holes, semiclassical black holes, or string balls. Such models have predicted signatures of particles with high transverse momenta. Noncommutative black holes remain an untested model of TeV-scale gravity that offers the starkly different signature of particles with relatively low transverse momenta. Considerations for a search for charged noncommutative black holes using the ATLAS detector will be discussed.

A black hole is predicted to be formed at the LHC if, as proposed by Thorne, the hoop conjecture is fulfilled by two partons from a proton-proton collision [9, 16]
Summary
Reasons why extra dimensions have not yet been discovered ATLAS and CMS have used 13 TV data from the 2015-2017 Run II campaign to search for semiclassical black holes, quantum black holes, and string balls. The absence of evidence for signatures of TeV-scale gravity at the LHC can be attributed to either one of three reasons. It could be that extra dimensions do exist, and that we have not discovered evidence of them because we need more energy to access them. Most excitingly, signatures of TeV-scale gravity may have already been produced at the LHC, but have either been hiding in signatures different than those we have used in searches or because they have been produced at a very low rate and the signal is diluted
