Associated production of the Z boson with a pair of top quarks in the left-right twin Higgs model
Abstract
In the context of the left-right twin Higgs (LRTH) model, we first examine the effects on the Zt\bar t production at the ILC and LHC. Our results show that the cross-sections can be significantly deviated from the standard model predictions and thus provide a good probe for the LRTH model. We also estimate the new production channel, Zt\bar T or Z\bar tT production, at the LHC. Compared with Zt \bar t production, we find that the Z t \bar T production can have a sizable production rate when the scale f is not too high. Considering the dominant decay mode T\rightarrow\phi^{+}b\rightarrow tb\bar b , we find that Z t\bar T final state has less background than Zt\bar t production and may likely be observable at the LHC.
