The Large Hadron Collider finds ‘intriguing anomalies’ that could rewrite the rules of physics

  • Experiment involved decay of B0 mesons to a pair of electrons or muons
  • In the Standard Model, muon should have identical interactions to electrons 
  • But, the researchers found that decays involving muons were less frequent

New findings at the Large Hadron Collider could shake up our current understanding of particle physics.

Researchers with CERN’s LHCb experiment have revealed the discovery of ‘intriguing anomalies’ that hint at explanations beyond the Standard Model.

The experiment found that some particles decay less often than expected under a particular set of circumstances, and researchers are now working to determine if this is sign of new physics phenomena, or simply a statistical error.

WHAT IT MEANS

In the Standard Model, this property predicts that ‘up to a small and calculable effect due to the mass difference, electron and muons should be produced with the same probability in this specific B0 decay.’

But, in the LHCb experiment, the researchers found that decays involving muons were less frequent.

As the Standard Model predicts electrons and muons have a high degree of symmetry, which has been supported in many studies, the discrepancies seen in the data could ‘signal new physics,’ according to CERN.

Still, the researchers note, it is too early for a firm conclusion.

While the findings are so far considered to be only of limited statistical significance, the observation supports similar phenomena seen in earlier studies, suggesting something new could be at play.

The experiments, presented today in a seminar at CERN, involved the decay of B0 mesons to an excited kaon and a pair of electrons or muons.

Despite being 200 times heavier, the muon is thought to have identical interactions to those of the electron based on a property known as lepton universality.

In the Standard Model, this property predicts that ‘up to a small and calculable effect due to the mass difference, electron and muons should be produced with the same probability in this specific B0 decay.’
