Chapter 2. Economical 3-3-1 Model
In Section 2.1. we recall the idea of constructing the two-Higgs
triplet 3-3-1 model. In Section 2.2., masses of charged gauge bosons
are given and an exact diagonalization of neutral ones and their
mixings are presented. Because of the mixings, currents in this
model have unusual features in the neutrino sectors which are presented in Section 2.3. In Section 2.4., constraints on the parameters
of the model and some phenomena are sketched. We outline the
main features in the last section—Section 2.5.
