End of a theory? Sypersymmetry and the LHC

Now this really could change things, as reported via the BBC:

LHC results put supersymmetry theory 'on the spot'
By Pallab Ghosh, Science correspondent, BBC News
Results from the Large Hadron Collider (LHC) have all but killed the simplest version of an enticing theory of sub-atomic physics. Researchers failed to find evidence of so-called "supersymmetric" particles, which many physicists had hoped would plug holes in the current theory.

As sympersymmetry (SUSY) or or correctly in this case the Minimal Supersymmetric Standard Model seems not to be true then we're in for some radical changes in particle physics.

Recently, LHC narrowed the range of the mass of Higgs to 115-140GeV which itself is suggesting that the Higgs mechanism might have to have change or that there could be a number of Higgs in there. Some are now even pushing the claim that Higgs might not exist at all which in the light of the M-SUSY results would radically change our understanding of physics.

Trouble is, SUSY and the standard model have a long history, very beautiful mathematics and very good predictive powers...and who said science was boring?

Next in the firing line: string theory ..... ( XKCD
