The Large Hadron Collider at CERN is currently being rebooted after a 拢97million refit. It's due to re-open in March after being switched off for two years.

The refit will allow particles to be fired at twice the previous energy.

Claire Lee, a physicist at Cern, told Today "Up until this point we've only run at half of the energy that the LHC was designed for. We're now expecting the LHC to be able to run at...almost the energy it was designed for".

Dave Charlton, spokesperson of the ATLAS Project, added "When we turn on again with these new higher energies we should have the capability to start producing new particles and look for new processes, if they're there."

"It's actually a very open question, we don't know what physics we're going to find when we switch on again."
