Neutrino masses are obtained within SU(4)LxU(1)X electroweak gauge models with spontaneous symmetry breaking by simply exploiting the tree level realization of certain dimension-five effective operators. The scalar sector needs not to be enlarged, since these operators are constructed as direct products among scalar multiplets already existing in the model. There is a unique generic matrix for Yukawa couplings in the neutrino sector, while the charged leptons are already in their diagonal basis. The experimentally observed phenomenology in the neutrino sector is obtained as a natural consequence of this particular approach.

    The finite temperature behavior of the scalar sector of models with U(1) and/or SU(2) gauge symmetries beyond the standard model is investigated. As the temperature decreases, complicated patterns of symmetry breaking and restoration appear in a model with U3(1) gauge symmetry. The results will...

    We apply a unitary approach together with a set of hidden-gauge Lagrangians to study the vector-vector interaction. We study the case of the ρ(ω)D* interaction within the model. In I = 1/2 we get strong enough attraction to bind the system. Concretely, we get one resonance for each spin J...

    In a gauge theory with SU(5) broken to SU(2)×U(1), the Higgs mass squared receives only logarithmic divergence from all scalar-gauge interactions at one loop. The same pattern of gauge symmetry breaking can be achieved without any scalar fields in a five-dimensional model.

    Applied to the electroweak interactions, the theory of Lie algebra extensions suggests a mechanism by which the boson masses are generated without resource to spontaneous symmetry breaking. It starts from a gauge theory without any additional scalar field. All the couplings predicted by the...

    In this study, we consider a flat Friedmann-Robertson-Walker (FRW) universe in the context of Palatini f( R) theory of gravity. Using the dynamical equivalence between f( R) gravity and scalar-tensor theories, we construct a point Lagrangian in the flat FRW spacetime. Applying Noether gauge...

    In F-term supergravity inflation models, scalar fields other than the inflaton generically receive a Hubble induced mass, which may restore gauge symmetries during inflation and phase transitions may occur during or after inflation as the Hubble parameter decreases. We study topological defect...

    The formation of a thick brane in five-dimensional space-time is investigated when warp geometries of AdS type are induced by scalar matter dynamics and triggered by a thin-brane defect. The scalar matter is taken to consist of two fields with O(2) symmetric self-interaction and with manifest...
