A simplified 2HDM with a scalar dark matter and the galactic center gamma-ray excess
Due to the strong constraint from the LUX experiment, the scalar portal dark matter cannot generally explain a gamma-ray excess in the galactic center by the annihilation of dark matter to bb¯. With the motivation of eliminating the tension, we add a scalar dark matter to the aligned two-Higgs-doubl...
