Program of Searches with the CMS Detector for Signals from Multidimensional Low-Energy Gravity at the Large Hadron Collider

This article, presented on behalf of the Compact Muon Solenoid (CMS) Collaboration, gives a generalizing survey of the results of the CMS experiment that concern searches for Kaluza–Klein excited states of the graviton (KK modes) and for microscopic multidimensional black holes, quantum black holes, and string balls within multidimensional low-energy gravity. The present analysis relies on data obtained during the first (2010–2012) and second (2015–2018) stages of operation of the Large Hadron Collider (LHC) in proton–proton collisions at the center-of-mass energies of 7, 8, and 13 TeV. The results of experimental searches are interpreted in terms of constraints on the space of parameters of the theoretical models being studied. Also, further prospects for the HL-LHC mode and for the possible Future Circular Collider (FCC) are discussed briefly.
