Supersymmetry sideswiped. (“No, it doesn’t work that way!” says LHC.)

BBC reports that the Large Hadron Collider is messing up a perfectly neat theory about how the universe fits together:

Supersymmetry, or SUSY, has gained popularity as a way to explain some of the inconsistencies in the traditional theory of subatomic physics known as the Standard Model.

The new observation, reported at the Hadron Collider Physics conference in Kyoto, is not consistent with many of the most likely models of SUSY.

Prof Chris Parkes, who is the spokesperson for the UK Participation in the LHCb experiment, told BBC News: “Supersymmetry may not be dead but these latest results have certainly put it into hospital.”

Researchers at the LHCb detector … have measured the decay between a particle known as a Bs Meson into two particles known as muons. It is the first time that this decay has been observed and the team has calculated that for every billion times that the Bs Meson decays it only decays in this way three times.

If superparticles were to exist the decay would happen far more often. This test is one of the “golden” tests for supersymmetry….

If supersymmetry is not an explanation for dark matter, then theorists will have to find alternative ideas to explain those inconsistencies in the Standard Model. So far researchers who are racing to find evidence of so called “new physics” have run into a series of dead ends.
