H.Sung Cheon (천화성, 千和聖) - DESY Theory workshop 2008

So we introduce two new terms of Qing-Hong Cao, Ernst Ma, and

L = L 1DM + g 1
Λ H† HS T S + g 2

After breaking the EW gauge symmetry (In order to have acceptable particle
masses), the Φ-dependent part of the scalar potential is given by
V = 1 2 (m2 Φ 0 + λν 2 EW)Φ 2 + λ s
4 Φ4 + λ 2 h2 Φ 2 + λν EW hΦ 2
In addition we have the new effective interaction terms,
L Int = −(m S
