Neutral currents in reduced minimal 3-3-1 model

Understand

This work is devoted for gauge boson sector of the recently proposed model based on SU(3)_C X SU(3)_L X U(1)_X group with minimal content of leptons and Higgses.

• The limits on the masses of the bilepton gauge bosons and on the mixing angle among the neutral ones are deduced.
• Using the Fritzsch anzats on quark mixing, we show that the third family of quarks should be different from the first two.
• We obtain a lower bound on mass of the new heavy neutral gauge boson as 6.051 TeV.
