Cern experiment hints at new force of nature | Large Hadron Collider | The Guardian: In physics parlance, the result has a significance of 3.1 sigma, meaning the chance of it being a fluke is about one in 1,000. While that may sound convincing evidence, particle physicists tend not to claim a new discovery until a result reaches a significance of five sigma, where the chance of it being a statistical quirk are reduced to one in a few million.
