|Abstract:||By applying copositivity criterion to the scalar potential of the economical 3-3-1 model, we derive necessary and sufficient bounded-from-below conditions at tree level. Although these are a large number of intricate inequalities for the dimensionless parameters of the scalar potential, we present general enlightening relations in this work. Additionally, we use constraints coming from the minimization of the scalar potential by means of the orbit space method, the positivity of the squared masses of the extra scalars, the Higgs boson mass, the Z gauge boson mass and its mixing angle with the SM Z boson in order to further restrict the parameter space of this model.|
