Black Hole Production at the LHC by Standard Model Bulk Fields in the Randall-Sundrum Model
arXiv:hep-ph/0611224 · doi:10.1016/j.physletb.2007.01.045
Abstract
We consider the production of black holes at the LHC in the Randall-Sundrum(RS) model through the collisions of Standard Model(SM) fields in the bulk. In comparison to the previously studied case where the SM fields are all confined to the TeV brane, we find substantial suppressions to the corresponding collider cross sections for all initial states, i.e., , and , where represents a light quark or anti-quark which lie close to the Planck brane. For quarks, which are closer to the TeV brane, this suppression effect is somewhat weaker though quark contributions to the cross section are already quite small due to their relatively small parton densities. Semi-quantitatively, we find that the overall black hole cross section is reduced by roughly two orders of magnitude in comparison to the traditional TeV brane localized RS model with the exact value being sensitive to the detailed localizations of the light SM fermions in the bulk.
