Multiple solutions in supersymmetry and the Higgs

Weak-scale supersymmetry is a well motivated, if speculative, theory beyond the Standard Model of particle physics.
It solves the thorny issue of the Higgs mass, namely: how can it be stable to quantum corrections, when they are expected to be 1015 times bigger than its mass? The experimental signal of the theory is the production and measurement of supersymmetric particles in the Large Hadron Collider experiments.
No such particles have been seen to date, but hopes are high for the impending run in 2015. Searches for supersymmetric particles can be difficult to interpret.
Here, we shall discuss the fact that, even given a well defined model of supersymmetry breaking with few parameters, there can be multiple solutions.
These multiple solutions are physically different, and could potentially mean that points in parameter space have been ruled out by interpretations of LHC data when they shouldn’t have been.
We shall review the multiple solutions and illustrate their existence in a universal model of supersymmetry breaking.
