Description

With protection by an extra Z2 symmetry, non-SM Higgs boson could be a possible DM candidate. As an example, we consider the singlet extension of the two-Higgs-doublet model. Intriguingly, the dark matter interaction with nucleons in the model could violate isospin symmetry and thus lead to a solution to alleviating the conflict between LUX and other direct detection experiments. Simultaneously, the value of \tan\beta; is well-determined. The consequences from the latest cosmological observations and experimental exclusion limits will be discussed.
