Probing and Identifying Large Extra Dimensions at the Hadron and Lepton Colliders.
A. A. Pankov and A. V. Tsytrinov

We explore the capability of high energy hadron and lepton colliders, LHC and ILC, to distinguish spin-2 Kaluza-Klein towers of gravitons exchange from other new physics effects which might be conveniently parameterized by the four-fermion contact interactions. We find that the LHC and ILC with planned energies and luminosities will be capable of discovering and identifying graviton exchange effects in the ADD scenario with the cutoff parameter of order 4.8 - 8.8 TeV depending on the energy and luminosity.
Key words: high energy colliders, extra dimensions, four-fermion contact interaction
