DescriptionThe unification of the Standard Model of physics with the theory of general relativity is one of the most salient problems facing theoretical physicists today. A search is presented for strongly-coupled string theory, a possible resolution to this problem. At an accelerator experiment, evidence for this theory could manifest as a shutting off of all Standard Model processes. This phenomenon is referred to as extinction, beyond some energy threshold related to an extinction scale M. The search presented here utilizes 5.0 inverse femtobarns of data taken in proton-proton collisions at sqrt(s) = 7 TeV. These data were taken by the Compact Muon Solenoid (CMS) experiment, situated at the Large Hadron Collider (LHC). The Standard Model predicts the formation of collinear streams of particles known as jets, with one of the highest production cross-sections of any process expected in proton-proton collisions. The transverse momentum distribution of all jets in data is constructed, and compared to that expected by the Standard Model, as well as that expected by extinction physics for various values of M. The standard model and extinction hypotheses are expressed in terms of an explicit calculation of perturbative quantum chromodynamics (pQCD) at next-to-leading order. No significant evidence of an extinction signature is observed, and an upper limit of 3.2 TeV is set on the scale M at 95% C.L.
