- Conclusion
๏ the discovery of Higgs is a remarkable triumph in particle physics ๏ a light weakly coupled Higgs argues for new physics beyond SM ๏ Search for new physics calls for both high precision machine and high energy machine ๏ 100 TeV pp machine:
- probe energy frontier: non-SM Higgs, naturalness connection, dark
matter, BSM particles,...
- precision, H coupling, V3,V4 couplings (cosmo connection), EW couplings
- SM physics: new phenomena
An exciting journey ahead of us!
