  • Rodriguez, Marcos Cardoso (2007)
    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 ...
  • Mariotto, Cristiano Brenner; Espíndola, Danúbia Bueno; Rodriguez, Marcos Cardoso (2011)
    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 = ...
  • Rodriguez, Marcos Cardoso (2010)
    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 ...
  • Rodriguez, Marcos Cardoso; Mariotto, Cristiano Brenner (2008)
    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 ...
  • Maekawa, Claudio Masumi; Rodriguez, Marcos Cardoso (2006)
    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 ...
  • Maekawa, Claudio Masumi; Rodriguez, Marcos Cardoso (2008)
    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 ...
  • Montero, Juan Carlos; Pleitez, Vicente; Rodriguez, Marcos Cardoso (2002)
    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 ...
  • Montero, Juan Carlos; Pleitez, Vicente; Rodriguez, Marcos Cardoso (2004)
    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 ...
  • Rodriguez, Marcos Cardoso (2007)
    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 ...
  • Rodriguez, Marcos Cardoso; Dong, Paulo Vicente; Huong, Douglas; Longa, Herman (2007)
    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 ...
