Abstract:
A search for the extinction of QCD jet production is presented using data collected with the CMS detector corresponding
to 10.7 of proton-proton collisions at 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.Note:
