Tests of Low Scale Quantum Gravity in e{sup -}e{sup -} and {gamma}{gamma} Collisions
Arkani-Hamed, Dimopoulos and Dvali have recently proposed that gravity may become strong at energies near 1 TeV due to the existence of large extra dimensions thus ''removing'' the hierarchy problem. In this talk we examine the exchange of towers of Kaluza-Klein gravitons and their influence on Moller scattering as well as the production of pairs of massive gauge bosons in {gamma}{gamma}collisions. These tower exchanges lead to a set of new dimension-8 operators that can significantly alter the Standard Model expectations for these processes. In the case of {gamma}{gamma}collisions, the role of polarization for both the initial state photons and the final state gauge bosons in improving sensitivity to graviton exchange is emphasized.
