Impact of polarized beams for Higgs, Electroweak and Dark Matter Physics — •Gudrid Moortgat-Pick — University of Hamburg, Hamburg, Germany — Wackerweg 1

Future Electron-Positron Linear Collider Designs (ILC, CLIC, HALHF) offer high-energy, polarized beams and high-precision measurements. In the talk we discuss the impact of polarized beams for the detection of the Higgs couplings, CP-violation effects and Dark Matter candidates with respect to the model distinction in different Beyond the Standard Models (MSSM, 2HDMS, inflation models). The current experimental bounds have been taken into account and involved parameter scans have been performed.
