Title: Gravitationally induced quantum superposition reduction with large extra dimensions

Abstract

A gravity-driven mechanism (''objective reduction'') proposed to explain quantum state reduction is analyzed in light of the possible existence of large extra dimensions in the Arkani-Hamed, Dvali, Dimopoulos scenario. By calculating order-of-magnitude estimates for nucleon superpositions, it is shown that if the mechanism at question is correct, constraints may be placed on the number and size of extra dimensions. Hence, measurement of superposition collapse times (e.g. through diffraction or reflection experiments) could represent a new probe of extra dimensions. The influence of a time-dependent gravitational constant on the gravity-driven collapse scheme with and without the presence of extra dimensions also is discussed.

  • CERN LHC provides a good experimental platform to perturbatively probe the fundamental gravity scale up to several TeV, with the precise value depending on the number of extra dimensions. The leading experimental signal of the graviton at the LHC is from the process pp{yields}jet+Ee{sub T}, where Ee{sub T} stands for the transverse missing energy. A detailed discussion on the hadronic production of the real graviton through hard subprocesses: qq{yields}G+g, g+q{yields}G+q, and g+g{yields}G+g have been studied within the quantum gravity theory with large extra dimensions. The main theoretical uncertainties together with the dominant standard model background to these processes, e.g. qq{yields}Z{supmore » 0}+g and g+q{yields}Z{sup 0}+q with Z{sup 0} further decaying into neutrinos, have also been discussed. It is found that only in a certain jet energy region and with a certain number of extra dimensions can the quantum gravity signal be distinguished from the background, which inversely lead to the effective scale M{sub D} to be probed up to (8.8{+-}0.9) TeV for two extra dimensions and (5.9{+-}0.5) TeV for four extra dimensions with sufficient integrated luminosity, e.g. 100 fb{sup -1}, at CERN LHC.« less

For {gamma} + E{sub T} and jet + E{sub T} candidate samples corresponding to 2.0 fb{sup -1} and 1.1 fb{sup -1} of integrated luminosity respectively, they observe good agreement with standard model expectations and obtain a combined lower limit on the fundamental parameter of the large extra dimensions model, M{sub D}, as a function ofmore » the number of extra dimensions in the model.« less
  • A search for large extra spatial dimensions via virtual-graviton exchange in the diphoton channel has been carried out with the CMS detector at the LHC. No excess of events above the standard model expectations is found using a data sample collected in proton-proton collisions at sqrt(s) = 7 TeV and corresponding to an integrated luminosity of 36 inverse picobarns. New lower limits on the effective Planck scale in the range of 1.6-2.3 TeV at the 95% confidence level are set, providing the most restrictive bounds to date on models with more than two large extra dimensions.
  • In theories with large extra dimensions, we study the top-spin correlations at the Large Hadron Collider. The s-channel process mediated by graviton Kaluza-Klein modes contributes to the top-antitop pair production in addition to the standard model processes, and affects the resultant top-spin correlations. We calculated the full density matrix for the top-antitop pair production. With the fundamental scale of the extra dimensional theory below 2 TeV, we find a sizable deviation of the top-spin correlations from the standard model one.
  • We present the results of searches for large extra dimensions in samples of events with large missing transverse energy Ee{sub T} and either a photon or a jet produced in pp collisions at {radical}(s)=1.96 TeV collected with the Collider Detector at Fermilab II. For {gamma}+Ee{sub T} and jet+Ee{sub T} candidate samples corresponding to 2.0 and 1.1 fb{sup -1} of integrated luminosity, respectively, we observe good agreement with standard model expectations and obtain a combined lower limit on the fundamental parameter of the large extra dimensions model M{sub D} as a function of the number of extra dimensions in the model.
