Search to Forward-Backward Asymmetry for new Z’ gauge boson
The Forward-Backward (FB) asymmetry is studied in the framework of the several models for the new Z’ Boson gauge in e+e- collision. It is shown that these physical observables are sensitive to these models, which would be useful in the search of new physics at coming LHC experiments.
