TL;DR

This paper explores a supersymmetric model with vector-like generations, demonstrating that strong gauge coupling effects can simultaneously explain the Higgs boson mass and muon g-2 anomaly within certain parameter regions.

Contribution

It introduces a supersymmetric model with vector-like generations where strong renormalization-group effects enable simultaneous explanation of Higgs mass and muon g-2.

Findings

Existence of parameter regions explaining both Higgs mass and muon g-2

Strong gauge coupling effects induce sizable Yukawa couplings

Model provides a unified explanation within supersymmetry

Abstract

We study the Higgs boson mass and the muon anomalous magnetic moment (the muon $g-2$) in a supersymmetric standard model with vector-like generations. The infrared physics of the model is governed by strong renormalization-group effects of the gauge couplings. That leads to sizable extra Yukawa couplings of Higgs doublets between the second and vector-like generations in both quark and lepton sectors. It is found with this property that there exist wide parameter regions where the Higgs boson mass and the muon $g-2$ are simultaneously explained.
