LARGE HADRON COLLIDER SEARCH FOR GLUINO

The Large Hadron Collider (LHC) is due to restart next month after an energy-boosting upgrade, following the crucial discovery of the Higgs boson:

Doubling the LHC collision energy may take it into the domain of dark matter particles, as predicted by Supersymmetry, which is  a theoretical addition to the Standard Model of particle physics. Most of the matter in the Universe is believed to be in the form of dark matter. There may be many dark matter particles, partners to the ordinary matter particles. Initial candidates for discovery by the LHC are the gluino (the partner of the gluon which holds the quarks together inside protons and neutrons) and the neutralino.

Professor Beate Heinemann of the University of California at Berkley, a spokeswoman for the Atlas experiment at the LHC, says: 'We hope that we're just now at this threshold that we're finding another world, like antimatter for instance. We found antimatter in the beginning of the last century. Maybe we'll now find supersymmetric matter.'

Dr Michael Williams of Massachusetts Institute of Technology (MIT) said: 'Finding any particle that could be a dark matter candidate is nice because we could start to understand how it affects the galaxy and the evolution of the universe, but it also opens the door to whatever is on the other side, which we have no idea what is there.'

Comment: These are adventurous and exciting times for particle physics and cosmology. A feeling that we may be just on the verge of major new discoveries that could change our view of the universe.
