The new (g- 2) μ result and the μν SSM
The μνSSM is a highly predictive alternative model to the MSSM. In particular, the electroweak sector of the model can explain the longstanding discrepancy between the experimental result for the anomalous magnetic moment of the muon, (g- 2)μ, and its Standard Model prediction, while being in agreem...

The μνSSM is a highly predictive alternative model to the MSSM. In particular, the electroweak sector of the model can explain the longstanding discrepancy between the experimental result for the anomalous magnetic moment of the muon, (g- 2)μ, and its Standard Model prediction, while being in agreement with all other theoretical and experimental constraints. The recently published MUON G-2 result is within 0.8σ in agreement with the older BNL result on (g- 2) μ. The combined result was announced as aμexp = (11659206.1 ± 4.1) ×10-10, yielding a new deviation from the Standard Model prediction of Δaμ = (25.1 ± 5.9) × 10-10, corresponding to 4.2σ. Using this improved bound we update the analysis in the μνSSM as presented in Kpatcha et al. (Eur Phys J C 81(2):154. arXiv:1912.04163 [hep-ph], 2021) and set new limits on the allowed parameters space of the electroweak sector of the model. We conclude that significant regions of the model can explain the new (g- 2) μ data |
