GUT-inspired SUSY and the muon g-2 anomaly: prospects for LHC 14 TeV

Understand

We consider the possibility that the muon g-2 anomaly, $\delta(g-2)$, finds its origins in low energy supersymmetry (SUSY).

• In the general MSSM the parameter space consistent with $\delta(g-2)$ and correct dark matter relic density of the lightest neutralino easily evades the present direct LHC limits on sparticle masses and also lies to a large extent beyond future LHC sensitivity.
• The situation is quite different in GUT-defined scenarios where input SUSY parameters are no longer independent.
• We analyze to what extent the LHC can probe a broad class of GUT-inspired SUSY models with gaugino non-universality that are currently in agreement with the bounds from $\delta(g-2)$, as well as with the relic density and the Higgs mass measurement.
