报告摘要 The long-lived particles (LLPs) are important targets when searching for beyond standard model physics. The future lepton collider with an additional far detector may play a unique role in searching for LLPs. In this talk, I will present the feasibility of installing far detectors at future e^-e^+colliders. We consider various locations and designs of far detectors and investigate their potentials for discovering LLPs in the physics scenarios including exotic Higgs decays, heavy neutral leptons, and the lightest neutralinos. The results show that such new experiments with far detectors at future lepton colliders may extend and complement the sensitivity reaches of the experiments at future lepton colliders with usual near detectors, and of the present and future experiments at the LHC.
