On Gaugino Dominated Dark Matter

Using the neutral gauginos of 2L YSU U 1 and hybridization ideas below the GUT scale, we approach the Dark Matter particle within the Minimal Supersymmetric Standard Model. In the energy range GUT ZM M where supergravity effects can be ignored, it is proposed that such DM particle could be inter-preted in terms of a mixture of Bino and Wino states with a lower bound mass 65DMM GeV 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
