Implications of low and high energy measurements on SUSY models

TL;DR

This paper discusses the conflicting implications of recent low and high energy measurements on supersymmetry models, highlighting tensions between experimental data and theoretical predictions, especially regarding the muon g-2 anomaly and Higgs mass.

Contribution

It analyzes the impact of recent experimental bounds and measurements on the viability of SUSY models, emphasizing the tension between the muon g-2 anomaly and Higgs mass predictions.

Findings

High lower bounds on unknown particle masses increase tension in SUSY interpretations.

The muon g-2 anomaly suggests significant new physics, conflicting with SUSY explanations given recent Higgs mass measurements.

The Higgs mass around 125 GeV supports SUSY but complicates explanations for the muon g-2 deviation.

Abstract

New Physics searches at the LHC have increased significantly lower bounds on unknown particle masses. This increases quite dramatically the tension in the interpretation of the data: low energy precision data which are predicted accurately by the SM (LEP observables like M_W or loop induced rare processes like B --> X_s gamma or B_s --> mu+mu-) and quantities exhibiting an observed discrepancy between SM theory and experiment, most significantly found for the muon g-2, seem to be in conflict now. (g-2)_mu appears to be the most precisely understood observable which at the same time reveals a 3-4 sigma deviation between theory and experiment and thus requires a significant new physics contribution. The hints for a Higgs of mass about 125 GeV, which is precisely what SUSY extensions of the SM predict, seem to provide a strong indication for SUSY. At the same time it brings into serious trouble the interpretation of the (g-2)_mu deviation as a SUSY contribution.
