Constrained Supersymmetry after the Higgs Boson Discovery: A global analysis with Fittino

TL;DR

This paper conducts a comprehensive global fit analysis of the constrained minimal supersymmetric standard model (CMSSM), integrating collider, astrophysical, and Higgs data to evaluate its viability post-Higgs discovery.

Contribution

It provides the first combined fit of CMSSM parameters including Higgs signal rates, collider limits, and astrophysical data within the Fittino framework, highlighting the model's remaining viability.

Findings

Higgs mass and LHC constraints significantly restrict parameter space

Acceptable fit quality achieved when Higgs signal rates are included

The analysis supports the continued relevance of CMSSM post-Higgs discovery

Abstract

We present preliminary results from the latest global fit analysis of the constrained minimal supersymmetric standard model (CMSSM) performed within the Fittino framework. The fit includes low-energy and astrophysical observables as well as collider constraints from the non-observation of new physics in supersymmetric searches at the LHC. Furthermore, the Higgs boson mass and signal rate measurements from both the LHC and Tevatron experiments are included via the program HiggsSignals. Although the LHC exclusion limits and the Higgs mass measurements put tight constraints on the viable parameter space, we find an acceptable fit quality once the Higgs signal rates are included.
