Supersymmetry remains elusive

Results from the Large Hadron Collider (LHC) at CERN point show that the rare B-meson to a muon and antimuon decays are consistent with the standard model. It was hoped that the details of these rare events would provide evidence of supersymmetry, at least for energies up to 8 TeV.

Researchers working on the LHCb experiment announced their results on Monday at the Hadron Collider Conference in Kyoto. A preprint is available on the arXiv.

However, this is not actually inconsistent with supersymmetry, the measurements are still compatible with some supersymmetric theories. For example, Prof. Gordon Kane argues that models based on superstring compactifications are quite compatible with the LHCb results. You can read more about this here.

The energy of the collisions at the LHC will be increased from the current 8 TeV to 14 TeV, which will be engineered over the 2013–2014 shutdown. It is possible that signals of supersymmetry may be found at this higher energy.

Right now it seems that the standard model has again passed at the tests, which include he discovery of the Higgs and the details of the rare B-meson decays.

    1. The SM is the model to beat, and so far nature is not helping us find out what is beyond. There has to be more to nature than the standard model, there are questions it cannot address, gravity is just one of them.

      And on that, nature has also conspired not to give hints to what should be the quantum theory of gravity. General relativity also passes all the tests.

      Unless nature starts to play ball, we will never find out.
