Compton Scattering at the NLC and Large Extra Dimensions

摘要

We study Compton scattering,(gamma) e(yields)(gamma)e, in the context of the recent proposal for Weak Scale Quantum Gravity (WSQG) with large extra dimensions. It is shown that, with an ultraviolet cutoff M(sub S)(approx) 1 TeV for the effective gravity theory, the cross section forthis process at the Next Linear Collider (NLC) deviates from the prediction of the Standard Model significantly. Our results suggest that, for typical proposed NLC energies and luminosities, WSQG can be tested in the range 4 TeV(approx) less or equal to M(sub S)(approx) less or equal to 16 TeV, making(gamma)e(yields)(gamma)e an important test channel.
