摘要：

We calculate the production rates of the second Kaluza-Klein (KK) photon gamma((2)) and Z boson Z((2)) at the LHC including all significant processes in the minimal universal extra dimension (MUED) model. For discrimination of the MUED model from other TeV scale models in hadron collider experiments, gamma((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), gamma((2)) and Z((2)) are produced 10(6) - 10(2) for the compactification scale between 400 GeV and 2000 GeV.
