Search for TeV-scale gravity signatures in final states with leptons and jets with the ATLAS detector at s = 8 TeV

German Colon, University of Massachusetts Amherst

Abstract

Theories postulating extra spatial dimensions into which the gravitational field can propagate provide interesting extensions to the Standard Model addressing the hierarchy problem. These frameworks predict TeV-scale gravity signatures, such as black hole or string ball production, that could be observed at the Large Hadron Collider. Said black holes decay into a high multiplicity of particles with typical energies ranging in the few 100 GeV. The production of events with multiple high transverse momentum particles including charged leptons and jets is measured, using 13.0 fb−1 of proton-proton collision data recorded by the ATLAS detector during 2012 at s = 8 TeV. No excess beyond Standard Model expectations is observed, and upper limits on the cross sections for non-Standard Model production of these final states are set.^
