American physicists could not confirm an observation announced in April that was then described as the possible discovery of a new elementary particle, or even an unknown force of nature, they said Monday.
Researchers at the Fermilab laboratory in Chicago (Illinois, North) had discovered a suspicious irregularity in their data that could be a major breakthrough in particle physics.
They believed then another unknown force in addition to gravity, electromagnetism and strong and weak nuclear forces.
But another team from the international research group working and DZero at Fermilab could not reproduce this observation.
“We looked at from two hundred trillion particle collisions in the accelerator and have not been able to see this excess (…) in the data reported by our colleagues,” he said in a statement Dmitri Denisov A spokesperson for DZero.
For over a year, physicists have studied this irregularity in the data from Fermilab, which houses a particle accelerator called the Tevatron, the most powerful until 2008, when the Europeans have opened the “Grand Collider hadrons “the French-Swiss border.
Both teams are now looking to form “a working group to coordinate a study on analysis of the two experiments” with physicists from both groups, says Fermilab in a statement.
“Independent verification of any new observation is the basic principle of scientific research and we have two Tevatron experiments had their design can verify each other,” said Stefan Soldner-Rembold, another spokesperson for DZero.
DZero includes about 500 physicists from 19 countries and works including the “Higgs boson”, one of the last missing pieces of the Standard Model, the theory developed here nearly 40 years by physicists to describe all particles and forces in the universe .
