We study the s-channel single top quark production at the LHC in the context of extra dimension theories, including the Kaluza-Klein (KK) decomposition. It is shown that the presence of the first KK excitation of W gauge boson can
reduce the total cross section of s-channel single top production considerably if MWKK ∼ 2.2 TeV (3.5 TeV) for 7 TeV (14TeV) in proton-proton collisions. Then the results will be compared with the impacts of other beyond Standard Model (SM) theories on the cross section of single top s-channel. The possibility of distinguishing different models via their effects on the production cross section of the s-channel is discussed.
