Revisiting the Inert Scalar Dark Matter with Vector-like Quarks
Revisiting the Inert Scalar Dark Matter with Vector-like Quarks
The inert doublet model (IDM), a minimal extension of the Standard Model (SM), provides a scalar dark matter (DM) candidate that belongs to the additional Higgs doublet. The model faces challenges in achieving the correct relic abundance for compressed spectra and DM masses in the high-mass range. In this work …
