In light of very recent E989 experimental result, we investigate the possibility that heavy sparticles explain muon g−2 anomaly. We focus on bino-smuon loop in an effective SUSY scenario, where a gravitino plays role dark matter and other are heavy. Due to enhancement left-right mixing smuons by higgsinos, contribution can sizably increase prediction value. Under collider vacuum stability constraints, find TeV scale bino smuon still account for new The implications LHC phenomenology also discussed.
