In order to guarantee the stability of the dark matter candidates,<br />
1. Z 2 symmetry is conserved<br />
2. Spontaneously symmetry break the EW gauge group<br />
<br />
After the spontaneously EW symmetry breaking, the singlet scalar<br />
dependent part of the scalar potential is given by<br />
V = 1 2 (m2 0 + λv2 EW)φ 2 + λ s<br />
4 φ4 + λv EW φ 2 h + h 2 φ2 h 2
