We point out the production of the charginos and neutralinos in electron-electron process in several supersymmetric models, in order to show that the International Linear Collider can discover double charged charginos if ...

In this paper, we investigate the influence of nuclear effects in the production of gluinos in nuclear collisions at the Large Hadron Collider, and estimate the transverse momentum dependence of the nuclear ratios RpA = ...

We recall the many obstacles which seemed, long ago, to prevent supersymmetry from possibly being a fundamental symmetry of Nature. We also present their solutions, leading to the construction of the supersymmetric extensions ...

Gluinos are expected to be one of the most massive sparticles (supersymmetric partners of usual particles) which constitute the Minimal Supersymmetric Standard Model (MSSM). The gluinos are the partners of the gluons and ...

We consider the mass generation for the usual quarks and leptons in some supersymmetric models. The masses of the top, the bottom, the charm, the tau and the
muon are given at the tree level. All the other quarks and the ...

É apresentada a extensão supersimétrica do modelo econômico 3–3–1. As equações de restrição e a identificação do bóson de calibre estabelecem uma relação entre os valores esperados de vácuo (VEVs) nos elementos superior e ...

In a previous work we applied a discrete symmetry (Z′ 2 ) in order to light fermions acquire mass only at one loop level. This symmetry and the assumption of alignment between fermions and sfermions allow us to avoid FCNC ...

We build a complete supersymmetric version of a 3-3-1 gauge model using the superfield formalism. We
point out that a discrete symmetry, similar to R symmetry in the minimal supersymmetric standard model, is
possible to ...

We consider the supersymmetric extension of the 3-3-1 model with right-handed neutrinos.We study the mass spectra in the scalar and pseudoscalar sectors, and for a given set of the input parameters, we
find that the ...

We build the complete supersymmetric version of a 3-4-1 gauge model using the super-eld formalism. We point out that a discrete symmetry, similar to the R-symmetry in the minimal supersymmetric standard model, is possible ...
