## Revisiting the real graviton effects at CERN LHC within the quantum gravity theory with large extra dimensions

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 »
