Electroweak physics has been tested and exploited at current LHC very comprehensively. It seems to be in an auto-piloting mode that our job becomes either searching BSM physics or improving the precision of SM measurement. Our recent work proposes a new channel, W boson 4-lepton decay, which people have not paid enough attention, but the current LHC is able to measure. Furthermore, this channel can be used to constrain other BSM model, such as L_\mu-L_\tau.
In the latter half of my talk, I would like to switch to the SM precision measurement at future 10 TeV muon collider. Especially, I will discuss the Higgs total width measurement via vector boson fusion at muon collider and the global constraints on Higgs effective couplings, showing the sensitivity of future muon collider.
