Simple 3-3-1 model and implication for dark matter

Understand

We propose a new and realistic 3-3-1 model with the minimal lepton and scalar contents, named the simple 3-3-1 model.

• The scalar sector contains two new heavy Higgs bosons, one neutral H and another singly-charged H^\pm, besides the standard model Higgs boson.
• There is a mixing between the Z boson and the new neutral gauge boson (Z').
• The \rho parameter constrains the 3-3-1 breaking scale (w) to be w>460 GeV.
