Title: The Prospects of Probing New Physics @ Future Lepton Colliders
Abstract: The discovery of the Higgs boson in 2012 heralds a new era of particle physics. With 125GeV of mass, almost all decay channels of the Higgs boson have sizable branching ratios, opening up a golden window for probing the Nature. Since then, multiple designs have been proposed, including CEPC, FCC-ee, and ILC250. I will first summarize the major observables and their precisions. And then elaborate the prospects of probing new physics with these observables in the framework of the Standard Model Effective Theory (SMEFT). Although lepton collider is a precision machine, it can already probe new physics scale up to tens of TeV and hence can definitely serve an explorer for future hadron colliders.
