In this work we show that 3-3-1 model with right-handed neutrinos has a natural WIMP dark matter candidate. It is a complex scalar with mass of order of some hundreds of GeV which carries two units of lepton number, a scalar bilepton. This makes it a very peculiar WIMP, very distinct from Supersymmetric or Extra-dimension candidates. Besides, although we have to make some reasonable assumptions...

Dark matter is usually distinguished from ordinary matter by an odd-even parity, i.e. the discrete symmetry Z 2. The new idea of Z 3 dark matter is proposed with a special application to generating radiative Majorana neutrino masses in two-loop order.

We present the dark matter extension of the minimal supersymmetric standard model by one more two component stable fermion NR toward explaining the recent rising high energy positron spectrum of the PAMELA data. The needed coupling can arise in the flipped-SU(5) GUT.
