Supersymmetry is under attack at Large Hadron Collider! Save Our Sparticles (SOS!)


The Supersymmetry theory, around since the 1960s, proposes that all fermions (the fundamental particles of matter) have corresponding bosons (the carriers of basic forces). At the moment, including the Higgs, there are five boson types, which doesn’t match the 12 fermion types that exist.
 
Researchers at the Large Hadron Collider have detected one of the rarest particle decays seen in Nature, writes Pallab Ghosh, Science correspondent, for the BBC News, while noting the finding deals a significant blow to the theory of physics known as supersymmetry.

The problem is that the LHC outputs are increasingly eliminating the mass levels at which supersymmetry may exist. In the latest work, detailed at the Large Hadron Collider conference taking place in Kyoto, a new BS Meson decay rules out one of the proposed energies for supersymmetry.
 
As noted by the BBC and The Registrer, one attraction of supersymmetry is that as-yet-undiscovered and very massive particles would account for some of the universe’s dark matter. For example, a galaxy spinning faster than it should given what we know about its mass might contain particles from the “supersymmetry zoo”, giving it the right mass.
 
Ashley WennersHerron and Kathryn Jepsen, writing for Symmetry Magazine, report that scientists might need to go beyond the Standard Model to explain the mass of the Higgs-like boson observed at the Large Hadron Collider July 4, 2012. It is noted that even if the Higgs boson completes the puzzle, some of its pieces still refuse to fit. Scientific American updates the story.
