SUPERHEAVY DARK MATTER IN THE SUPERSYMMETRIC ECONOMICAL 3-3-1 MODEL

DO THI HUONG

We suggest the supersymmetric particles contained in the supersymmetric economical 3-3-1 model were produced during the heating time. They have not been thermodynamic equilibrium when it froze out. It leads to the lightest supersymmetric particle can be a good candidate for superheavy dark matter. With assumption the lightest supersymmetric particle is Bino, we show that the correct contribution of the superheavy dark matter (SHDM) species to the present critical density requires the Bino mass is order 10^12 GeV and there is not exists a large mass hierarchy of the superpartner in the considered model.
