Abstract: Pseudo-Goldstone dark matter coupled to the Standard Model via the Higgs portal offers an attractive framework for phenomenologically viable pseudoscalar dark matter. It enjoys natural suppression of the direct detection rate due to the vanishing of the relevant (tree level) Goldstone boson vertex at zero momentum transfer, which makes light WIMP-like dark matter consistent with the strong current bounds. In this work, we explore prospects of detecting pseudo-Goldstone dark matter at the LHC, focusing on the vector boson fusion channel with missing energy. We find that, in substantial regions of parameter space, relatively light dark matter (m(chi) <150 GeV) can be discovered in the high luminosity run as long as it is produced in decays of the Higgs-like bosons.
