A Novel Approach to Fine-Tuned Supersymmetric Standard Models -- Case of Non-Universal Higgs Masses model

TL;DR

This paper introduces a new method for exploring supersymmetric models by mapping experimental constraints to fundamental parameters, revealing novel particle mass patterns and explaining the muon g-2 discrepancy with less fine tuning.

Contribution

It proposes a novel approach to analyze supersymmetric models by focusing on experimental constraints at low energy, uncovering new mass patterns and addressing the muon g-2 anomaly.

Findings

Identified a new superparticle mass pattern with light first two generation squarks and heavy stops.

Demonstrated the muon g-2 discrepancy can be explained within 1 sigma using this method.

Provided a more efficient way to explore parameter space in supersymmetric models.

Abstract

Discarding the prejudice about fine tuning, we propose a novel and efficient approach to identify relevant regions of fundamental parameter space in supersymmetric models with some amount of fine tuning. The essential idea is the mapping of experimental constraints at a low energy scale, rather than the parameter sets, to those of the fundamental parameter space. Applying this method to the non-universal Higgs masses model, we identify a new interesting superparticle mass pattern where some of the first two generation squarks are light whilst the stops are kept heavy as 6TeV. Furthermore, as another application of this method, we show that the discrepancy of the muon anomalous magnetic dipole moment can be filled by a supersymmetric contribution within the 1 {\sigma} level of the experimental and theoretical errors, which was overlooked by the previous studies due to the required terrible fine tuning.
