A first evidence of the CMSSM is appearing soon

TL;DR

This paper investigates the coannihilation region of the CMSSM, aligning it with current experimental constraints, and predicts observable signatures for near-future experiments to test this supersymmetric scenario.

Contribution

It provides the first detailed analysis of the CMSSM coannihilation region consistent with recent experimental data and offers testable predictions for upcoming collider and dark matter detection experiments.

Findings

Allowed parameter space consistent with 125GeV Higgs and relic abundances

Predicted SUSY particle spectra and decay rates

Feasibility of testing the scenario in near-future experiments

Abstract

We explore the coannihilation region of the constrained minimal supersymmetric standard model (CMSSM) being consistent with current experimental/observational results. The requirements from the experimental/observational results are the 125GeV Higgs mass and the relic abundances of both the dark matter and light elements, especially the lithium-7. We put these requirements on the caluculated values, and thus we obtain allowed region. Then we give predictions to the mass spectra of the SUSY particles, the anomalous magnetic moment of muon, branching fractions of the B-meson rare decays, the direct detection of the neutralino dark matter, and the number of SUSY particles produced in 14TeV run at the LHC experiment. Comparing these predictions with current bounds, we show the feasibility of the test for this scenario in near future experiment.
