报告摘要：
Multiple future lepton colliders have been proposed, offering powerful tools for precise studies of electroweak (EW) physics. This talk will first give a brief overview and then focus on two selected topics. The first concerns the EW dipole operators of the bottom quark, often omitted in SMEFT analyses. Using the process $e^+e^- \to b \bar{b}$ at future lepton colliders, we explore the subtle interplay between linear and quadratic effects, and show that multiple-energy runs are important for resolving coefficient degeneracies. The other topic is Z/W pole physics at a future muon collider. Although muon colliders cannot run at the Z-pole, they can probe electroweak by taking advantage of the high energy and large luminosity. We study the vector boson fusion processes of WW/WZ/W$\gamma$ to fermion pairs, and examine their potential to probe the dimension-6 operators that directly modify fermion couplings to the Z/W. Using kinematic distributions, the precision is generally comparable to future $e^+e^-$ colliders. Together, these studies highlight the strong potential for EW probing in the next lepton collider era.
