With regard to the Large Hadron Collider, the Higgs boson gets all the press but other potential discoveries could be more exciting and easier to detect.
However, if the theorists are right, before it ever finds the Higgs, the LHC will see the first outline of something far bigger: the grand, overarching theory known as supersymmetry. SUSY, as it is endearingly called, is a daring theory that doubles the number of particles needed to explain the world. And it could be just what particle physicists need to set them on the path to fresh enlightenment.
If you haven't been keeping up with particle physics for the past few years (as I haven't), this will bring you up to speed a bit.
