A Short Story Of Supersymmetry

I've mentioned earlier of the uncomfortable position that Supersymmetry is on right now due to the lack of any evidence found so far from the LHC. Wired Science talks to Lawrence Krauss for a short explanation on what Supersymmetry is, for people who are curious. And certainly, is take on the lack of evidence so far is dead on.
The problem is that neither the LHC nor its recently decommissioned American counterpart, the Tevatron, have seen any strong evidence for new, heavy particles during their experiments. Though they keep searching at higher energy ranges, the particle accelerators don’t turn up any new superpartners.

“As we exclude more and more energy ranges, the supersymmetry models that most easily keep the scales separate get more and more contrived,” said Krauss.

Already, experiments have excluded the simplest supersymmetric theories. Physicists can keep tweaking their theories but after a while these fine-tunings begin to seem arbitrary.
I think that if the LHC sees no indication of supersymmetry, the theory in its present form, will lose much of its appeal.
