H$\rightarrow$invisible at the ILC with SiD
Abstract
The Standard Model (SM) predicts a branching ratio of the Higgs boson decaying to invisible particles of (0.001), though current measurements have only set upper limits on this value. The small SM-allowed rate can be enhanced if the Higgs boson decays into new particles such as dark matter. Upper limits have been placed on BR(Hinv.) by ATLAS and CMS at (0.1), but the hadron environment limits precision. The ILC `Higgs factory' will provide unprecedented precision of this electroweak measurement. Studies of the search for Hinvisible processes in simulation are presented with SiD, a detector concept designed for the ILC. Preliminary results for expected sensitivity are provided, as well as studies considering potential systematics limitations.
