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

Dr. Yaser Ayazi from IPM


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 $M_{W_{KK}}\sim2.2~ \rm TeV$ ($3.5~ \rm TeV$) for $7~\rm TeV$ ($14~\rm TeV$) 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.
