dc.descriptionWe discuss the collider signatures of electroweak (1,0)-mode excitations in the framework of two universal extra dimension (2UED) at the LHC and ILC. In general, pair production of electroweak (1,0)-mode particles of 2UED gives rise to multi lepton plus missing transverse momentum signal. Upto 1/R = 400 GeV two lepton plus missing transverse momentum signal and upto 1/R = 600 GeV three lepton plus missing transverse momentum signal stands over the $5σ$ standard deviation of the Standard Model background at the LHC with $100 fb^{-1}$ integrated luminosity. At ILC we study single photon plus missing energy signal from the production of U(1) gauge boson in association with a U(1) spinless adjoint. With proper choice of beam polarization, signal strength is greater than $5σ$ standard deviation of the Standard Model background almost upto the kinematic limit of the collider.
