Reports that the Large Hadron Collider had detected the first possible signs of the elusive Higgs boson particle were "wrong", experts have said.
Last month, an internal memo outlining a possible signal from the Higgs picked up at the LHC was leaked on to the web.
But cross-checks of the data collected by the Atlas experiment have since found no signal.

The director-general of Cern, Rolf-Dieter Heuer, said that Cern's management was "not very amused" by the leak.
He commented: "This should be a lesson to journalists not to report results they might see from blogs. If we do discover something and we are sure of it we will announce it officially. Any other news is speculative."
