The Impact of Kaluza-Klein Excited W Boson on the Single Top at LHC and Comparison with other Models

Abstract

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 $M_{W_{KK}}\sim 2.2\mathrm{TeV}$ ($3.5\mathrm{TeV}$) for $7\mathrm{TeV}$ ($14\mathrm{TeV}$) 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.
