7. Higgs et al Mechanism 7

8. 8 Finger-printing the Higgs boson Is it: the Higgs Boson of the Standard Model? another type of Higgs boson? something that looks like a Higgs boson but is actually more complicated?

9. 9 Finger-printing the Higgs boson Is it: the Higgs Boson of the Standard Model? another type of Higgs boson? something that looks like a Higgs boson but is actually more complicated?  Measurements of the Higgs couplings to the different species of quarks, leptons and gauge bosons are the key to answering these questions

21. ILC Plan in Japan ► Japanese HEP community proposes to host ILC based on the “staging scenario” to the Japanese Government.  ILC starts as a 250GeV Higgs factory, and will evolve to a 500GeV machine.  Technical extendability to 1TeV is to be preserved. Yamauchi
