Probing the Higgs couplings and self-coupling at future lepton colliders in the EFT framework
Jiayin Gu (JGU Mainz)

We study the reach on the Higgs coupling constraints at future lepton colliders in a global effective-field-theory framework. The impact and complementarity of different measurements, at different center-of-mass energies and for several beam polarization configurations, are discussed in detail. We also study the sensitivities to the Higgs self-coupling at future lepton colliders under this framework.
