Signatures of Extra Dimensions at e-gamma and gamma-gamma Colliders
Hooman Davoudiasl
Abstract
We study the processes γ -> γ and γγ-> γγ, in the context of the proposal for Weak Scale Quantum Gravity (WSQG) with large extra dimensions. With an ultraviolet cutoff MS 1 TeV for the effective gravity theory, the cross sections obtained for these processes at the Next Linear Collider (NLC), with the γan γγoptions, deviate from the predictions of the Standard Model significantly. Our results suggest that, for typical proposed NLC energies and luminosities, the predictions of WSQG can be tested in the range 1 TeV MS 10 TeV, making γan γγcolliders important tools for probing WSQG.
