| Abstract: A search for black holes using a data sample corresponding to an integrated luminosity of 2.2 fb$^{-1}$ collected with the CMS experiment at the LHC in pp collisions at a center-of-mass energy of 13 TeV in 2015 is presented. No excess characteristic of a black hole production or other new physics signals resulting in energetic multiparticle final states was observed. Standard model background, dominated by QCD multijet production, was determined exclusively from control regions in data, without any reliance on simulation. Model-independent limits on the cross section of a new physics signal in these final states are set and further interpreted in terms of limits on black hole production. In the context of models with large extra dimensions, semiclassical black holes with masses below $\sim$ 8.7 TeV and quantum black holes with masses below $\sim$ 8 TeV are excluded by this search, thus significantly extending limits set in the LHC Run 1. | ||
