The physics programme of linear e+e- colliders spans from the Z-Pole deep into the TeV range. Therefore, all Standard Model particles and their interactions are covered by the scientific programme of linear colliders. Beam polarisation allows for testing all aspects of the electroweak and the Higgs sector. New physics would lead to unique patterns of deviations from the Standard Model...
At energies above 500 GeV processes such as di-Higgs production or associated top-Higgs production open up. Both processes will profit from the clean environment of e+e- collisions that will allow for a direct measurement of the Higgs self-coupling and an unambiguous determination of the CP properties of the Higgs boson.
The Higgs particle is intimately coupled to the top quark. Therefore,...
