Sfermion masses in the supersymmetric economical 3-3-1 model
Sfermion masses and eigenstates in the supersymmetric economical 3-3-1 model are studied. By lepton number conservation, the exotic squarks and superpartners of ordinary quarks are decoupled. Due to the fact that in the 3-3-1 models, one generation of quarks behaves differently from other two, by R-parity conservation, the mass mixing matrix of the squarks in this model are smaller than that in...
متن کاملA supersymmetric 3 - 3 - 1 model
We build the complete supersymmetric version of a 3-3-1 gauge model using the superfield formalism. We point out that a discrete symmetry, similar to the R-symmetry in the minimal supersymmetric standard model, is possible to be defined in this model. Hence we have both R-conserving and R-violating possibilities. Analysis of the mass spectrum of the neutral real scalar fields shown that in this...
متن کاملSupersymmetric economical 3-3-1 model
The supersymmetric extension of the economical 3-3-1 model is presented. The constraint equations and the gauge boson identification establish a relation between the vacuum expectation values (VEVs) at the top and bottom elements of the Higgs triplet χ and its supersymmetric counterpart χ′. Because of this relation, the exact diagonalization of neutral gauge boson sector has been performed. The...
متن کاملA supersymmetric 3-4-1 model
The full symmetry of the so called Standard Model (SM) is the gauge group SU(3)c ⊗ SU(2)L ⊗ U(1)Y . Nevertheless, the SM is not considered as the ultimate theory since neither the fundamental parameters, masses and couplings, nor the symmetry pattern are predicted. Even though many aspects of the SM are experimentally supported to a very accuracy, the embedding of the model into a more general ...
متن کاملNeutralinos and charginos in supersymmetric economical 3-3-1 model
Fermion superpartners neutralinos and charginos in the supersymmetric economical 3-3-1 model are studied. By imposition R parity, their masses and eigenstates are derived. Assuming that Bino-like is dark matter, its mass density is calculated. The cosmological dark matter density gives a bound on mass of LSP neutralino in the range of 20 ÷ 100 GeV, while the bound on mass of the lightest slepto...
