Comment Would measure Higgs properties more accurately (Score 1) 292
The LHC isn't that great for precision measurements of Higgs properties (mass, production cross section, branching ratios for decays). If there's a small deviation from the SM, the ILC could find what the LHC can't.
For supersymmetry, I'm not sure if the ILC could see anything at all given how high the masses have been pushed by the LHC already, but upping the energy from the current 8 TeV to 13 or 14 and adding 10-100 times the data can still give the LHC a chance to find SUSY.
Large extra dimensions was always a long shot. There's really no good case from theory for that showing up at current energies.
