Such large statisticswill allow for a wide range of possibilities in the realm of precision Higgs measurements.Several Higgs couplings will be measured to a percent level precision, including the secondgeneration muon yukawa coupling. The Higgs to invisible branching fraction will be probedto a level of few 10−4and the rate of longitudinally polarized vector bosons produced invector boson scattering will be measured with 2% precision.
