Hopes fade for new particle discovery as Large Hadron Collider data found to be ‘statistical fluke’

But eight months after scientists hinted at the possibility of findings “more exciting than the discovery of the Higgs [Boson] itself" from the Large Hadron Collider, the latest data has shown it to be nothing more than a statistical blip.
“Basically we see nothing,” said Tiziano Camporesi, a chief scientific spokesman at the European Centre for Nuclear Research (Cern), where the huge atom-smashing machine is located.
In December, early unconfirmed readings of an unusually high number of gamma rays during a collision were identified as possibly being produced by the decay of a new particle.
But additional research in the following months showed the data to be a random “statistical fluke,” said Dave Charlton, another Cern spokesman.
Studying similar types of rays eventually led to the tentative confirmation of the existence of the Higgs Boson particle, dubbed the “God particle”, in 2013.
In May, theoretical physicist Csaba Csaki, who isn't involved in the experiments, said: “If this is really true, then it would possibly be the most exciting thing that I have seen in particle physics in my career — more exciting than the discovery of the Higgs itself.”
However, while the new data ruled out any particle existing at the energy level the scientists had been looking at, disappointment may be the most serious outcome of the findings.
“It's a shame there wasn't a particle there, but there aren't any big ideas that would rise or fall on it being there,“ said Sean Carroll, a California Institute of Technology physicist.
The Large Hadron Collider, the world's largest and most powerful particle accelerator, was built between 1998 and 2008.
It is operating beyond expectations in its second extended run – which is ongoing – and is providing more data than expected, Mr Charlton and Mr Camporesi said, according to the Press Association.
Physicists from Cern have presented more than 50 new results, but none of them are breakthrough findings that would change current theory.
“Stay tuned, I don't think we have lost hope yet,” Mr Camporesi said.
