Muong−2in focus point SUSY

Abstract

We point out that the anomaly of the muon $g\ensuremath{-}2$ can easily be explained in a focus point supersymmetry (SUSY) scenario, which realizes the seminatural SUSY. Among known focus point SUSY scenarios, we find that a model based on Higgs-gaugino mediation works with a mild fine-tuning $\mathrm{\ensuremath{\Delta}}=40--80$. We propose two new focus point SUSY scenarios where the anomaly of the muon $g\ensuremath{-}2$ is also explained. These scenarios are variants of the widely known focus point SUSY based on gravity mediation with universal scalar masses.
