Description
We explore signatures of large extra dimensions with a polarized electron/positron beam at the Joint Linear Collider (JLC). We point out that spin informations can be useful to study indirect signals for large extra dimensions due to spin-2 nature of Kaluza-Klein gravitons. The spin configurations of the top quark pair production at e+e- and γγ collisions provide an unique testing ground to search for effects of the large extra dimensions. Especially we show the forward-backward asymmetry is a good probe at e+e- → tt-bar process and we can define a new asymmetry observable effective for γγ → tt-bar process. (author)
