Explaining electron and muon g-2 anomaly in SUSY without lepton-flavor mixings

Abstract

We propose a SUSY scenario to explain the current electron and muon g - 2 discrepancies without introducing lepton flavor mixings. Threshold corrections to the Yukawa couplings can enhance the electron g - 2 and flip the sign of the SUSY contributions. The mechanism predicts a flavor-dependent slepton mass spectrum. We show that it is compatible with the Higgs mediation scenario.
