dc.descriptionWe discuss collider signatures of (1,1)-th Kaluza-Klein (KK) mode vector bosons in the framework of two universal extra dimension model, at a future electron-positron collider. Production of the (1,1)-th KK mode of electro-weak vector bosons (B(1,1), W3(1,1)), are considered in association with a hard photon. Without caring about the decay products of those vector bosons, one can measure the masses of these particles just by looking at the photon energy distribution. Once produced these particles dominantly decay to a pair of jets or to a pair of top quarks. Thus we look for a pair of jets or a pair of top quarks in association with a photon. Upto the kinematic limit of the collider, signals from the B(1,1) production and decay in both the above mentioned channels are greater than the $5σ$ fluctuation of the Standard Model background. However, the number of events from W3(1,1) production and decay is smaller and its detection prospect is not very good.
