TL;DR
This review summarizes the latest results from LHC proton-proton collision searches for exotic phenomena like extra dimensions, black holes, and dark matter, setting new limits but finding no evidence of physics beyond the Standard Model.
Contribution
It compiles and reviews the most recent experimental searches for various exotic phenomena at the LHC, highlighting the most stringent limits established to date.
Findings
No evidence of new physics observed.
Most stringent limits set on exotic phenomena.
Constraints on models of extra dimensions and dark matter.
Abstract
This review presents a selection of the final results of searches for various exotic physics phenomena in proton-proton collisions at sqrt(s)=7 and 8 TeV delivered by the LHC and collected with the ATLAS and CMS detectors in 2011 (5 fb-1) and in the first part of 2012 (4 fb-1). Searches for large extra dimensions, gravitons, microscopic black holes, long-lived particles, dark matter, and leptoquarks are presented in this report. No sign of new physics beyond the Standard Model has been observed so far. In the majority of the cases these searches set the most stringent limits to date on the aforementioned new physics phenomena.
