Anomalous muon magnetic moment in the inverse seesaw extended next-to-minimal supersymmetric standard model

Abstract

The present work investigates the possibility that both dark matter and the anomalous magnetic moment of the muon may be explained within the context of the inverse seesaw extended next-to-minimal supersymmetric Standard Model (ISS-NMSSM). In ISS-NMSSM, the newly introduced Higgs-neutrino Yukawa coupling ${Y}_{\ensuremath{\nu}}$ provides additional Higgsino-sneutrino loop contribution to $(g\ensuremath{-}2{)}_{\ensuremath{\mu}}$. If the deviation between the experimental observations and the Standard Model predictions of the anomalous muon magnetic moment is confirmed by the further experimental and theoretical studies, it can be explained naturally within the ISS-NMSSM framework without conflicting with the current stringent limits on the direct detection of dark matter and Large Hadron Collider searches.
