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