We study the signature of dilepton and a hard jet (ℓ+ℓ−j) via heavy new gauge boson production in split universal extra dimension scenario where the Kaluza-Klein parity is conserved but the Kaluza-Klein number is not. A hard cut to the jet energy effectively removes virtually all possible backgrounds and provides a handle to search of new physics involving new neutral heavy states as the Kaluza-Klein Z boson. The signature can be more generically used in search of other new states such as graviton and radion in warped extra dimension models.
