论文摘要
暗物质的一个有趣模型涉及一个隐藏的扇区与标准模型（SM）字段解耦，但某些门户相互作用除外。隐藏的Abelian Higgs模型的具体实现是将Sm Higgs玻色子的腐烂引起的一对新玻色子，称为$ Z _ {\ Mathrm {D}} $或暗光子。本说明探索了使用$ \ sqrt {s} = 250 $ GEV搜索ILC上这种暗光子的前景，其中深色光子迅速衰减。对于$ h \ rightarrow z {\ mathrm {d}} z _ {\ mathrm {d}}} \ rightarrow 4 \ ell $（$ \ ell = e，μ$）的最终状态，它遵循LHC的最近类似的类似搜索，而对于$ 2 \ ell2J $和$ 4J $ 4J $ 4J $ 4J $ 4J $ 4J。这项研究尚未获得SID财团的批准。
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 $H\rightarrow Z_{\mathrm{d}}Z_{\mathrm{d}}\rightarrow 4\ell$ ($\ell = e,μ$) 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.
