The extensions of the Standard Model based on SU(3)C⊗ SU(3)L⊗ U(1)X gauge group are known as 331 Models. Different properties, as the fermion assignment and the electric charges of the exotic spectrum, that defines a particular version of the model, are fixed by a parameter β. In this work, we explore a 331 version, set by the condition, where new particles arise with peculiar signatures as heavy fractionally charged leptons and electrical neutral quarks, among others. We examine different sectors of the model with emphasis in the Yukawa lagrangian of the new leptons, in order to study their branching fraction for scalar particles.
