Description
The International Linear Collider (ILC), with its technologically mature accelerator and detector designs and well-understood physics program, represents a realistic candidate for a future Higgs factory. Its staged energy program, the use of polarized beams, and the capability to reach center-of-mass energies up to 1 TeV offer unique sensitivity to deviations from Standard Model predictions in the Higgs sector and potential Beyond Standard Model (BSM) physics.
This presentation discusses the ILC’s potential to measure the branching ratio of Higgs boson decays into a fully invisible final state, $H \to ZZ^* \to \nu\nu\nu\nu$. The analysis is implemented within the Key4HEP framework in a modular way, allowing, for example, for straightforward comparisons between different detector concepts. Both technical aspects and first preliminary results will be presented.
