dc.descriptionWe explore signatures of large extra dimensions with a polarized electron/positrn 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 $e^+ e^- \to t \bar{t}$ process and we can define a new asymmetry observable effective for $γγ\to t \bar{t}$ process.
