CERN scientists, who announced last month that  the elusive Higgs boson had been  discovered, are going through the vast volume of material produced in the Geneva research center's Large Hadron Collider (LHC) for   "SUSY."
Formally known as Supersymmetry, SUSY is the idea that every one of the elementary particles that make up the universe and everything in it has an almost, but not quite identical, "superpartner."
"SUSY is still a very valid option and we have just started to constrain it on the energy scale," CERN particle physicist Oliver Buchmueller told Reuters.
"There are many regions on the map of where it should be that we have still to explore."
Its existence, many researchers say, was supported by the presumed discovery of the Higgs with which, physicists say, it is inextricably linked.
  Matt Strassler says, "it is a conjectured symmetry of space and time." It could be integrated with the theory of relativity to provide  an explanation of the laws of nature.
Physicists say SUSY may explain the dark matter   that makes up around 80 percent of the solid substance of the universe, and would provide backing for "string theory"
String theory holds that instead of particles, the universe is composed of microscopic strings.
