In physics baryon asymmetry is also known as material asymmetry. This issue is currently an interesting problem. Today, to explain baryon asymmetry, scientists use two mechanisms, Leptongenesis and Baryogenesis. A model having Baryogenesis must be satisfied the three conditions of A.Sakharov.

The thesis proposes a class for the new economic 3-3-1 model, called a simple 3-3-1 model, in order to address the mentioned problems. The simple 3-3-1 model considers the simplest lepton sector and the scalar sector. This setting leads to natural components of the inert fields such as scalar inert fields and right-handed neutrino.
