  Group theoretical realizations containing the electroweak sector of the
Standard Model are discussed from the supersymmetry point of view. Dynamical
breaking of the symmetry is performed and the corresponding quadratic (super
Yang-Mills) Lagrangian is obtained. Supercoherent states of the
Klauder-Perelomov type are defined to enlarge the symmetry taking into account
the geometry of the coset based in the simplest supergroup SU (2 | 1) as the
structural basis of the electroweak sector of the SM. The extended model is
superintegrable and the superconnection in the odd part takes a dynamical
character. The physical and geometrical implications of the additional degrees
of freedom interpreted as a hidden sector of the representation are briefly
discussed.
