  • The default Higgs mass points for SM Higgs productions are MH=125 and 800 GeV. The 800 GeV point has been chosen to avoid the unitarity problem even in s→infinite case. For Higgs self-coupling study, MH=125 GeV only.

  • The default Higgs mass points for SM Higgs productions are MH=125 and 800 GeV. The 800 GeV point has been chosen to avoid the unitarity problem even in s→infinite case. For Higgs self-coupling study, MH=125 GeV only.

  • The default Higgs mass points for SM Higgs productions are MH=125 and 800 GeV. The 800 GeV point has been chosen to avoid the unitarity problem even in s→infinite case. For Higgs self-coupling study, MH=125 GeV only.
