MUON ANOMALOUS MAGNETIC MOMENT IN THE SUPERSYMMETRIC ECONOMICAL 3-3-1 MODEL

Binh D.T, Huong D.T, Long H.N

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 \tan \gamma is large. We investigate the cases of both small and large values of \tan \gamma. 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 \tan \gamma (\tan \gamma\approx 5). Numerical estimation gives the mass of supersymmetric particles, the mass of gauginos m_G\approx 700 GeV, and the light slepton mass m_{\tilde{L}} of the order of \cO (100) GeV. When \tan{\gamma} is large (\tan{\gamma}\approx 60), the charged slepton mass m_{\tilde{L}} and the gaugino mass mG are \cO(1) TeV, while the sneutrino mass \approx 450 GeV is in the reach of the LHC.
