Resumen
By considering the 331 and the leftright symmetric models as low energy effective theories of the SU(3)_C⊗SU(3)_L⊗SU(3)_R (for short [SU(3)]^3) gauge group, alternative versions of these models are found. The new neutral gauge bosons of the universal 331 model and its flipped versions are presented; also, the leftright symmetric model and its flipped variants are studied. Our analysis shows that there are two flipped versions of the universal 331 model, with the particularity that both of them have the same weak charges. For the leftright symmetric model we also found two flipped versions; one of them new in the literature which, unlike those of the 331, requires a dedicated study of its electroweak properties. For all the models analyzed, the couplings of the Z′ bosons to the standard model fermions are reported. The explicit form of the null space of the vector boson mass matrix for an arbitrary Higgs tensor and gauge group is also presented. In the general framework of the [SU(3)]^3 gauge group, and by using the LHC experimental results and EW precision data, limits on the Z′ mass and the mixing angle between Z and the new gauge bosons Z′ are obtained. The general results call for very small mixing angles in the range 10^−3 radians and M_Z′>2.5 TeV.
