Abstract We propose an ultraviolet completion model for pseudo-Nambu-Goldstone mre93ll/a apple watch dark matter with a hidden U(1) gauge symmetry.Compared to previous 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 gauge fields would lead to dark matter decays.We find that the current bound on the ultra max dog shampoo 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.
