In the off-diagonal basis, we explore the effects of extra neutral gauge boson Z' predicted in two versions of SU (3)C × SU (3)L × U (1)X model on the spin configuration of the top quark pair production in the high energy linear e+e- collider (ILC). Our numerical results show that, the cross sections for the suppressed spin configurations can be enhanced with the effects of the Z' boson through the modification of the spin configuration by producing enough top quark pairs to be measured in the future ILC experiments, which provides the way to observe the effects of Z' predicted in the 3-3-1 model and discriminate the various versions of 3-3-1 model.

The left–right twin Higgs model predicts the existence of the new neutral gauge boson ZH. In the off-diagonal basis, we explore the effects of extra neutral gauge boson ZH on the spin configuration of the top-quark pair production in the high energy linear e+e- collider (ILC). We find that the new gauge boson ZH exchange can generate significant corrections to the differential cross-sections for the the [Formula: see text] and [Formula: see text] states. Furthermore, when the ZH mass MZH approaches the center-of-mass energy [Formula: see text], the cross-section resonance emerges. We expect that the effects of the new gauge boson ZH on the spin configurations of the top-quark pairs production might be observed in future ILC experiments.
