DarkLight Invisibles Effort

The DarkLight (Detecting A Resonance Kinematically with eLectrons Incident on a Gaseous Hydrogen Target) experiment at Jefferson Lab intends to study the process $e^{-}p\to e^{-}p{A}'$, with ${A}'$ being a hidden gauge boson decaying to $e^{-}e^{+}$. DarkLight will explore the A' mass region 10-100 MeV with sensitivity to couplings as low as ${\alpha }'/\alpha_{EM} \propto $ 10$^{\mathrm{-7\thinspace }}$with 1 ab$^{\mathrm{-1}}$ of data. The complete kinematic information provided by the DarkLight detector also permits a search for an invisibly decaying ${A}'$. In contrast to the numerous visible decay searches, both attempted and planned, there is considerably less data for the invisible decay. Furthermore, the limited data for invisibles' searches is from beam-dump and indirect decays, making this a unique measurement. This talk will focus on the invisibles effort for DarkLight, covering both the related physics and necessary instrumentation.
