Polarization Effects on the $e+e-\to W^{+}{W}^{-}$ process with Large Extra Dimensions

Abstract

We study large extra dimension effects on the polarizations of the $W$ pair and electron beam at the $e^{+}{e}^{-}\to W^{+}{W}^{-}$ process. It is shown that the measurements of the cross section for transversely polarized $W$ pair with the right-handed electron beam remarkably enhance the possibilities to see the low scale quantum gravity effects. Higher Linear Collider bounds on the string scale in this model can be obtained by using the left-handed electron beam.
