The Search for Dark Interactions with interpretation for dark matter

Ketevi Assamagan
Brookhaven National Laboratory

Hidden sector or dark sector states appear in many extensions to the Standard Model, to provide a candidate for the darkmatter in the universe or to explain astrophysical observations of positron excesses. A hidden or dark sector can be introduced with an additional U(1)d dark gauge symmetry. The presence of the dark sector could be inferred either from deviations from the SM-predicted rates of Drell-Yan (DY) events or from Higgs boson decays through exotic intermediate states. The discovery of the Higgs boson during Run 1 of the Large Hadron Collider opens a new and rich experimental program that includes the search for exotic decays H —> Z Zdark —> 4l and H —> Zdark Zdark —> 4l, where Zdark is a dark vector boson.
