  "abstract": "An interesting model of dark matter involves a hidden sector decoupled from Standard Model (SM) fields except for some portal interaction. A concrete realization of this is the Hidden Abelian Higgs Model, which gives rise to decays of the SM Higgs boson into a pair of new bosons, called $Z_{\\mathrm{d}}$ or dark photons. This note explores prospects for the search for such dark photons at the ILC with $\\sqrt{s}=250$ GeV, where the dark photons decay promptly. For the $H\\rightarrow Z_{\\mathrm{d}}Z_{\\mathrm{d}}\\rightarrow 4\\ell$ ($\\ell = e,\\mu$) final state, it follows closely recent similar searches at the LHC, while for the $2\\ell2j$ and $4j$ final states a multivariate analysis approach is used. This study has not been approved by the SiD consortium.",
