Main phenomenological features of the spontaneous CP violation in SU(3)   x U(1) models
  We analyze the phenomenological consequences of assuming spontaneous CP violation in an SU(3) x U(1) model with three Higgs triplets and one sextuplet. After the identification of the relevant physical scalars, we estimate the contributions to the parameters $\Delta m_K$, $\epsilon$ and $\epsilon'$ coming from the Higgs-fermion couplings.
