  • Scientists ‘will say they are 99.99% certain’ the particle has been found
  • Leading physicists have been invited to event – sparking speculation that Higgs Boson particle has been found
  • ‘God Particle’ gives particles that make up atoms their mass

Scientists at Cern will announce that the elusive Higgs boson ‘God Particle’ has been found at a press conference next week, it is believed.

Five leading theoretical physicists have been invited to the event on Wednesday – sparking speculation that the particle has been discovered.

Scientists at the Large Hadron Collider are expected to say they are 99.99 per cent certain it has been found – which is known as ‘four sigma’ level.

Neutrons Escaping to a Parallel World?


ScienceDaily (June 15, 2012) — In a paper recently published in European Physical Journal (EPJ) C, researchers hypothesised the existence of mirror particles to explain the anomalous loss of neutrons observed experimentally. The existence of such mirror matter had been suggested in various scientific contexts some time ago, including the search for suitable dark matter candidates.

Theoretical physicists Zurab Berezhiani and Fabrizio Nesti from the University of l’Aquila, Italy, reanalysed the experimental data obtained by the research group of Anatoly Serebrov at the Institut Laue-Langevin, France. It showed that the loss rate of very slow free neutrons appeared to depend on the direction and strength of the magnetic field applied. This anomaly could not be explained by known physics.

Berezhiani believes it could be interpreted in the light of a hypothetical parallel world consisting of mirror particles. Each neutron would have the ability to transition into its invisible mirror twin, and back, oscillating from one world to the other. The probability of such a transition happening was predicted to be sensitive to the presence of magnetic fields, and could therefore be detected experimentally.
