New Physics Off the $Z$-Pole: $e^+ e^- \rightarrow f \bar f$ at Future
Lepton Colliders
We explore the prospects for probing new physics (NP) beyond the Standard Model (SM) at future lepton colliders through precision measurements of $e^+e^-\to f{\bar f}$ observables off the $Z$ resonance. We consider interference between SM contributions and those arising from dimension-6, four-fermion effective operators that encode the effects of NP, …
