When will SUSY detection be, 10yrs 30yrs what will SUSY tell us about cosmology.
A better understanding of the universe will be the outgrowth of the discovery of the Higgs boson, according to a team of University of Oklahoma researchers. The team predicts the discovery will lead to supersymmetry or SUSY -- an extension of the standard model of particle physics. SUSY predicts new matter states or super partners for each matter particle already accounted for in the standard model. SUSY theory provides an important new step to a better understanding of the universe we live in.

The article is older than the Higgs discovery, and I would expect its authors misunderstood what the scientists said.

If nature is supersymmetric and if particle accelerator experiments find supersymmetric particles, then they might discover a dark matter candidate, which has implications for cosmology. In addition, supersymmetry would be relevant for the very early universe.

If SUSY is accurate, there's at least some chance that it will be detected at the LHC. Most SUSY models tend to have a number of particles in the low TeV range, which the LHC is probing today.

However, there are two big caveats:
1. The LHC doesn't produce very clean signals. We would need a lepton collider running at similar energies to really narrow down any discovery of supersymmetry. But lepton colliders are much, much harder to get to the same energies as are available at the LHC.
2. There's a large parameter space within supersymmetry models where supersymmetry could never be detected by the LHC.

So basically, how soon we detect SUSY (if at all) depends upon how lucky we are that the parameters of the universe put its detection within reach.

As for cosmology, obtaining a good understanding of supersymmetry would probably provide a precise answer as to what the dark matter particle is, as well as how the asymmetry between matter and anti-matter was produced in the early universe.
