N2 - We propose a new search for dark matter at the LHC, characteristic of scenarios beyond the Standard Model with a pseudoscalar portal between the visible and dark sectors. This search, leading to a bbZ(→â.,"â.,")+ET final state, reaches large regions of parameter space not probed by dark matter searches via multijet+ET, searches for new scalars and flavor bounds. We show that this search could be used to test the dark matter origin of the gamma-ray Galactic Center excess with LHC Run 2 data.
