Physics in high-energy electron-positron collisions

The next big project in particle physics after the LHC is supposed to be the International Linear Collider (ILC) (see Figure 1). This machine is a linear electron positron collider which will reach energies up to 1 TeV and will run a scientific programme which is complementary to the one of the LHC. Currently, this project is in its planning phase and much development work is being done all over the world.
We're constantly updating the physics case of the ILC, in particular in view of LHC results. This involves both phenomenological work and detector-level simulation studies, taking into account the the most recent design of the ILD detector and the accelerator. This work comprises the further optimisation of the ILD detector concept, and is incorporated into the SFB 676 ''Particles, Strings and the Early Universe''. We currently concentrate on Higgs, SUSY and Dark Matter processes.
