More transverse polarization signatures of extra dimensions at linear colliders

Polarization of both electron and positron beams at a future linear collider(LC) allows for the measurement of transverse polarization asymmetries. Theseasymmetries have been shown to be particularly sensitive to graviton or otherspin-2, $s-$channel exchanges in the process $e^+e^- \to f\bar f (f\neq e)$which allows for a doubling of the usual search reach. A question then arisesas to whether other $e^+e^-$ processes also show comparable sensitivity. Herewe extend our previous analysis to the set of final states $e^+e^-,W^+W^-,~2\gamma$ and $~2Z$ as well as to the M{\o}ller scattering process$e^-e^-\to e^-e^-$. We demonstrate that these reactions yield transversepolarization asymmetries which are somewhat less sensitive to graviton exchangethan are those obtained in our earlier analysis for $e^+e^-\to f\bar f$.Comment: 20 pages, 5 figs, LaTe
