Abstract We propose an ultraviolet completion model for pseudo-Nambu-Goldstone dark matter with a hidden U(1) gauge symmetry.Compared to previous PHOSSHATIDYLSERINE studies, this setup is simpler, introducing less interactions.Dark matter scattering off nucleons is highly suppressed by the ultraviolet scale and direct detection constraints can be easily evaded.The kinetic mixing between the hidden U(1) and the U(1)Y Wall Art (Set of 6) gauge fields would lead to dark matter decays.
We find that the current bound on the dark matter lifetime implies that the ultraviolet scale should be higher than 1010 GeV.The phenomenological constraints from the 125 GeV Higgs measurements, the dark matter relic density, and indirect detection of dark matter annihilation are also investigated.
