Received: May 11, 2015
We investigate the muon anomalous magnetic moment in the context of a supersymmetric version of the economical 3-3-1 model. We compute the 1-loop contribution of superpartner particles. We show that the contribution of superparticle loops become significant when is large. We investigate the cases of both small and large values of . We find the region of the parameter space where the slepton masses of a few hundred GeV are favored by the muon g-2 for small (). Numerical estimation gives the mass of supersymmetric particles, the mass of gauginos GeV, and the light slepton mass of the order of \cO (100) GeV. When is large (), the charged slepton mass and the gaugino mass mG are \cO(1) TeV, while the sneutrino mass GeV is in the reach of the LHC.
