Researchers have improved on previous observations, jumping from a 4.9 to a 5.9 Sigmalevel of certainly -- well beyond what is generally accepted as experimental confirmation.
But the Tevatron results are currently at the one-sigma level of certainty - a lower level of statistical significance than those presented by the Atlas and CMS teams.
Other experiments had seen some evidence of the D-meson's flipping, but this is the first that crosses the "five sigma" level of statistical significance that particle physicists use to denote an official discovery.
