Charged scalar portal dark matter with $U(1)_Y$ non-restoration and gravitational waves

We explore the possibility of reviving scalar singlet dark matter (DM) with a minimal extension by a charged singlet scalar which also leads to hypercharge non-restoration in the early Universe. The minimal scalar singlet DM annihilating via the Higgs portal is tightly constrained by direct-detection experiments, leavi...
