Focus Point Supersymmetry Redux

TL;DR

Focus Point Supersymmetry (FP SUSY) remains consistent with current experimental data, allowing multi-TeV squarks and sleptons without fine-tuning, and may explain the muon's magnetic moment deviation.

Contribution

This paper reevaluates FP SUSY in light of recent collider and cosmological data, highlighting its viability and proposing refined search strategies.

Findings

FP SUSY aligns with Higgs mass and dark matter constraints.

Heavy superpartners do not induce fine-tuning in the weak scale.

Potential explanation for muon's anomalous magnetic moment deviation.

Abstract

Recent results from Higgs boson and supersymmetry searches at the Large Hadron Collider provide strong new motivations for supersymmetric theories with heavy superpartners. We reconsider focus point supersymmetry (FP SUSY), in which all squarks and sleptons may have multi-TeV masses without introducing fine-tuning in the weak scale with respect to variations in the fundamental SUSY-breaking parameters. We examine both FP SUSY and its familiar special case, the FP region of mSUGRA/CMSSM, and show that they are beautifully consistent with all particle, astroparticle, and cosmological data, including Higgs boson mass limits, null results from SUSY searches, electric dipole moments, b -> s gamma, B_s -> mu^+ mu^-, the thermal relic density of neutralinos, and dark matter searches. The observed deviation of the muon's anomalous magnetic moment from its standard model value may also be explained in FP SUSY, although not in the FP region of mSUGRA/CMSSM. In light of recent data, we advocate refined searches for FP SUSY and related scenarios with heavy squarks and sleptons, and we present a simplified parameter space to aid such analyses.
