In the present work we study a model with an SU(2)_L x SU(2)_R x U(1)_X$ symmetry, with two scalar doublets. We start from a massless lagrangian, but by using the Coleman-Weinberg mechanism we obtain masses for both the gauge bosons and the scalars. We also calculate the renormalized effective potential, depending on the masses and couplings of the model. With this formalism we obtain two sets of gauge bosons, corresponding to the L and R sectors, in addition to the two scalars. We analyse the mass ratio of these sectors in order to obtain a hyerarchy between them. With an appropriate choice of parameters we can have the L particles in the SM range, while the R particles have much higher masses.
