A summary of the impact of the couplings on the Z′ acceptance times efficiency with respect to the SSM for models with altered fermion couplings or decay width, separately for the τlepτhad and τhadτhad channels. The most extreme impact on the acceptance is seen for models that couple only to left-handed or right-handed tau leptons: Z′L and Z′R, respectively. In each case the decay width is taken to be the same as for the SSM. For the decay width, the effect of a narrower decay width Z′narrow (Γ/mZ′ = 1%) or a wider decay width of Z′wide (Γ/mZ′ = 20%), compared to the SSM (Γ/mZ′ ≈ 3%), are shown.
