Muon g-2 in Focus Point SUSY

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