CERN 'unlikely' to discover new elementary particle

CERN 'unlikely' to discover new elementary particle

Scientists at CERN have given up their hopes of having discovered a new elementary particle.

Last December, two teams of physicists working at the Large Hadron Collider reported that they may have found traces of what could be a new fundamental constituent of nature.

The physicists said a bump on a graph signalling excess pairs of gamma rays was probably a statistical fluke, but they hoped it was more.

If real, the new particle would have opened a gap between the known and the unknown. In the few months after the announcement over 500 papers were written about the particle.

But at a scientific conference in Chicago, the teams reported that following much more data, the possibility was now unlikely.

The presentations were part of a report on the results so far this year from the collider.

After a rocky start, with an explosion in 2008, it is now running well and producing up to a billion proton-proton collisions a second.
