abstract="The minimal U(1)(X) extension of the Standard Model (SM) is a well-motivated new physics scenario, where anomaly cancellation dictates new neutral gauge boson (Z{\textquoteright}) couplings with the SM fermions in terms of the U(1)(X) charges of the new scalar fields. We investigate the SM charged fermion pair-production process for different values of these U(1)(X) charges at future e(-)e(+) colliders: e(+)e(-) -> f (f) over bar Apart from the standard gamma and Z-mediated processes, this model features additional s-channel (or both s and t-channel when f = e(-)) Z{\textquoteright} exchange which interferes with the SM processes. We first estimate the bounds on the U(1)(X) coupling (g{\textquoteright}) and the Z{\textquoteright} mass (M-Z{\textquoteright}) considering the latest dilepton and dijet constraints from the heavy resonance searches at the LHC. Then using the allowed values of g{\textquoteright}, we study the angular distributions, forward-backward (A(FB)), left-right (A(LB)), and left-right forward-backward (A(LR-FB)) asymmetries of the final states. We fmd that these observables can show substantial deviations from the SM results in the U(1)(X) model, thus providing a powerful probe of the multi-TeV Z{\textquoteright} bosons at future e(+)e(-) colliders.",
