Phys. Rev. Lett. 100, 131301 (2008) [4 pages]Signatures of Gravitational Fixed Points at the Large Hadron ColliderReceived 31 July 2007; published 1 April 2008 We study quantum-gravitational signatures at the CERN Large Hadron Collider (LHC) in the context of theories with extra spatial dimensions and a low fundamental Planck scale in the TeV range. Implications of a gravitational fixed point at high energies are worked out using Wilson’s renormalization group. We find that relevant cross sections involving virtual gravitons become finite. Based on gravitational lepton pair production we conclude that the LHC is sensitive to a fundamental Planck scale of up to 6 TeV. © 2008 The American Physical Society URL:
