History of Supersymmetric Extensions of the Standard Model
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 of the
Standard Model. Finally we discuss briefly the early experimental searches for
Supersymmetry.Comment: 40 pages, 10 figures, 3 Table
A supersymmetric 3-4-1 model
We build the complete supersymmetric version of a 3-4-1 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. We also discuss some phenomenological results coming from this
model.Comment: 23 pages, 2 figures and 1tabl
Mass Spectrum in the Minimal Supersymmetric 3-3-1 model
We consider the minimal supersymmetric extension of the 3-3-1 model. We study
the mass spectra of this model in the fermionic and gauge bosons sectors
without the antisextet. We also present some phenomenological consequences of
this model at colliders such as Large Hadron Collider (LHC) and International
Linear Collider(ILC).Comment: 39 pages, 3 Tables and 9 figure
Double Chargino Production in scattering
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
these particles really exist in nature.Comment: 9 pages, 9 figures, Talk given at CTP symposium on Supersymmetry at

Creation of blenders in the conservative setting
In this work we prove that each C^r conservative diffeomorphism with a pair
of hyperbolic periodic points of co-index one can be C^1-approximated by C^r
conservative diffeomorphisms having a blender.Comment: 4 figures, 16 figure
Left-right asymmetries and exotic vector-boson discovery in lepton-lepton colliders
By considering left-right (L-R) asymmetries we study the capabilities of
lepton colliders in searching for new exotic vector bosons. Specifically we
study the effect of a doubly charged bilepton boson and an extra neutral vector
boson appearing in a 3-3-1 model on the L-R asymmetries for the processes
, and and
show that these asymmetries are very sensitive to these new contributions and
that they are in fact powerful tools for discovery this sort of vector bosons.Comment: RevTeX, 22 pages, 12 eps figure
