在LHC上具有t t(bar)对的胶子的Kaluza-Klein激发的相关产生

Associated production of a Kaluza-Klein excitation of a gluon with a t t(bar) pair at the LHC

摘要:

在Randall-Sundrum模型中,胶子g_{KK}的Kaluza-Klein(KK)激发增强了与右手夸克的耦合。在这些模型中缺乏gg g_{KK}偶联的情况下,不可能从初始gg状态单次产生g_{KK}。因此,寻找LHC的其他产生机制变得非常重要。我们认为,相关的生产的g_{KK}与t t(酒吧)对是这样一种机制。我们的研究表明,通过这个过程,LHC可以探测2.8 - 2.9TeV范围内的KK胶子质量。

英文摘要:

In Randall-Sundrum models, the Kaluza-Klein (KK) excitations of the gluon, g_{KK} have enhanced couplings to the right-handed quarks. In the absence of a gg g_{KK} coupling in these models, the single production of a g_{KK} from an initial gg state is not possible. The search for other production mechanisms at the LHC, therefore, becomes important. We suggest that the associated production of a g_{KK} with a t t(bar) pair is such a mechanism. Our study shows that through this process the LHC can probe KK gluon masses in the range of 2.8 -- 2.9 TeV.
