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 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, or production, at the LHC. Compared with production, we find that the production can have a sizable production rate when the scale f is not too high. Considering the dominant decay mode , we find that final state has less background than production and may likely be observable at the LHC.
