| Abstract: A search for the extinction of QCD jet production is presented using data collected with the CMS detector correspondingto 10.7 $\text{fb}^\text{$-}$ of proton-proton collisions at $\sqrt{s}=8$ TeV. The extinction model studied in this analysis is motivated by the search for signatures of terascale gravity at the LHC and assumes the existence of string couplings in the strong-coupling limit. In this limit, the string model predicts suppression of all high transverse momentum standard model processes, including jet production, beyond a certain energy scale. A shape comparison between the measured transverse momentum spectrum of jets and the theoretical prediction is conducted. No significant deficit of events is found at high transverse momentum. A 95\% CL lower limit of 3.3 TeV is set on the extinction energy scale. | ||
