Higgs Factories: Higgs-Strahlung versus W-Fusion

Understand

Higgs factories will be able to measure Higgs properties, and in particular Higgs couplings with high precision.

• In a follow-up to an earlier analysis we study the impact of the Higgs-strahlung and vector boson fusion processes on the precision of the couplings determination.
• Provided theoretical uncertainties can be controlled, future Higgs factories will be able to measure Higgs couplings at the sub-percent level.
• In spite of their different strengths, base-line circular and linear designs can expect a surprisingly similar performance.
