  Using the neutral gauginos of SU(2)L* U(1)Y and hybridization ideas below the
GUT scale, we approach the Dark Matter particle within the Minimal
Supersymmetric Standard Model. In the energy range MGUT-MZ where supergravity
effects can be ignored, it is proposed that such DM particle could be
interpreted in terms of a mixture of Bino and Wino states with a lower bound
mass MDM sup or eq to 65GeV not far above the electroweak scale to account for
the observed Dark Matter density. We establish the theoretical origin of this
particle and study as well its compositeness and its mass bound.
