It is exciting time at the Large Hadron Collider. The experiment collected just enough data last year to look for supersymmetric particles which are predicted by the theory of Supersymmetry (SUSY). The Nature news has a piece, which tells us that the first results from the data shows no sign of such particles. This could potentially send us( well, particle theorists) back to the drawing boards.
“Yet there is growing anxiety that the theory, however elegant it might be, is wrong. Data from the Large Hadron Collider (LHC), a 27-kilometre proton smasher that straddles the French–Swiss border near Geneva, Switzerland, have shown no sign of the ‘super particles’ that the theory predicts1–3. “We’re painting supersymmetry into a corner,” says Chris Lester, a particle physicist at the University of Cambridge, UK, who works with the LHC’s ATLAS detector. Along with the LHC’s Compact Muon Solenoid experiment, ATLAS has spent the past year hunting for super particles, and is now set to gather more data when the LHC begins a high-power run in the next few weeks. If the detectors fail to find any super particles by the end of the year, the theory could be in serious trouble.”
