  We study quantum-gravitational signatures at the 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 renormalisation 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.
