Title	Dark sector as origin of tiny lepton masses and new sources of (g-2)_mu
Abstract	We propose a mechanism where charged lepton masses are generated at loop levels such that their smallness can naturally be explained by O(1) Yukawa couplings. This scenario can also explain the muon g-2 anomaly which has been more seriously the first result by FNAL. As an important consequence, the muon Yukawa coupling can significantly deviate from its SM prediction, and it will be tested at the High-Luminosity LHC and/or ILC. My presentation is based on the paper C.-W. Chiang and K. Yagyu, Phys. Rev. D 103 (2021) 11 (arXiv: 2104.00890 [hep-ph]).
