Description

We fully explore the prospect of using the off Z-pole run at
future lepton colliders to probe the new physics (NP) beyond the Standard Model (SM) via dimension-6 four-fermion effective operators. With interference between the dimesion-6 operator and SM diagram contributions to the e^+ e^- \rightarrow f \bar f scattering processes, the NP effects shows up at collision energy
off of the Z pole. The Z line shape scan is thus useful not just for the Z mass and width measurements, but
also for NP probes. I will discuss the key observable and uncertainties involved in order to reach a realistic prospects for the reach.
