Kaluza-Klein激发W玻色子对LHC单顶的影响及其与其它模型的比较

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

Seyed Yaser Ayazi, Mojtaba Mohammadi Najafabadi

摘要:

我们在额外维度理论的背景下研究了LHC的s通道单顶夸克产生,包括Kaluza-Klein(KK)分解。结果表明,在质子-质子碰撞中,如果对$W$($14\rm TeV$)采用$M_{W_{KK}}\sim2.2 \rm TeV$($3.5 \rm TeV$),则第一个KK激发的存在会使s沟道单顶产生的总截面大大减小.然后将计算结果与其他超越标准模型(SM)理论对单顶S形渠道截面的影响进行比较。讨论了不同模型对s型槽生产截面的影响。

英文摘要:

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 $7\rm TeV$ ($14\rm TeV$) 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.
