Heavy colored SUSY partners from deflected anomaly mediation

TL;DR

This paper introduces a deflected anomaly mediation model from SUSY QCD that produces a spectrum with heavy colored sparticles and light sleptons, potentially resolving the muon g-2 discrepancy and testable by future experiments.

Contribution

It presents a novel SUSY scenario with adjustable deflection parameters that naturally yields a favorable sparticle spectrum for muon g-2 resolution.

Findings

Heavy colored sparticles and light sleptons can coexist in the model.

The model can fully explain the muon g-2 anomaly within 1σ.

Future experiments like LUX-ZEPLIN can test the parameter space.

Abstract

We propose a deflected anomaly mediation scenario from SUSY QCD which can lead to both positive and negative deflection parameters (there is a smooth transition between these two deflection parameter regions by adjusting certain couplings). Such a scenario can naturally give a SUSY spectrum in which all the colored sparticles are heavy while the sleptons are light. As a result, the discrepancy between the Brookheaven $g_\mu-2$ experiment and LHC data can be reconciled in this scenario. We also find that the parameter space for explaining the $g_\mu-2$ anomaly at $1\sigma$ level can be fully covered by the future LUX-ZEPLIN 7.2 Ton experiment.
