Productions of second Kaluza-Klein gauge bosons in the minimal universal extra dimension model at LHC

We calculate the production rates of the second Kaluza-Klein (KK) photon γ(2) and Z boson Z(2) at the LHC including all significant processes in the minimal universal extra dimension model. For discrimination of the minimal universal extra dimension model from other TeV scale models in the hadron collider experiment, γ(2) and Z(2) play a crucial role. In order to discuss the discrimination and calculate their production rates, we derive effective Lagrangian containing KK number violating operators. We show that KK number violating processes are extremely important for the compactification scale larger than 800 GeV. We find that, with an integrated luminosity of 100 fb−1, the number of produced γ(2) and Z(2) are estimated as 106 102 for the compactification scale between 400 GeV and 2000 GeV.
