Compton scattering at the NLC and large extra dimensions - art. no. 044018

We study Compton scattering, gamma e --> gamma e, in the context of the rec ent proposal for weak scale quantum gravity (WSQG) with large extra dimensi ons. It is shown that, with an ultraviolet cutoff M(S)similar to 1 TeV for the effective gravity theory. the cross section for this process at the Nex t Linear Collider (NLC) deviates from the prediction of the standard model significantly. Our results suggest that, for typical proposed NLC energies end luminosities. WSQG can be tested in the range 4 TeV less than or simila r to M(S)less than or similar to 16 TeV, making gamma e --> gamma e an impo rtant test channel.
