New particle analysis findings may change physics as we all know it

A subatomic particle generally known as a muon is disobeying the essential legal guidelines of physics, in keeping with preliminary outcomes from two separate experiments debuted on Wednesday.

The Muon g-2 experiment on the Department of Energy’s Fermi National Accelerator Laboratory showed that elementary particles known as muons are behaving in a manner that’s not predicted by the physicist’s finest principle, generally known as the Standard Model of particle physics, the Associated Press reported.

A staff of over 200 researchers advised that the particles are not doing what is anticipated of them when they’re spun round in two completely different long-term experiments performed within the United States and Europe, hinting at a possible overhaul of the rulebook that physicists have lengthy used to grasp the universe on the subatomic degree.


Muons, that are 200 occasions as large as their cousin, the electron, are electrically charged particles with a property known as spin, behaving as if they’ve inside magnets.

The Standard Model predicts the anomalous magnetic second very exactly. If the quantum foam comprises further forces or particles not identified to the Standard Model, it could tweak the muon g-factor much more.

“This quantity we measure reflects the interactions of the muon with everything else in the universe. But when the theorists calculate the same quantity, using all of the known forces and particles in the Standard Model, we don’t get the same answer,” mentioned Renee Fatemi, a physicist on the University of Kentucky and the simulations supervisor for the Muon g-2 experiment. “This is strong evidence that the muon is sensitive to something that is not in our best theory.”

The discovery is claimed doubtlessly to result in a breakthrough within the understanding of the universe as substantial because the 2012 discovery of the Higgs boson, a particle that imbues different particles with mass, in keeping with the New York Times.

When muons flow into inside the muon g-2 magnet, they work together with a quantum foam of subatomic particles shifting out and in of existence. Interactions with these non permanent particles have an effect on the g-factor, inflicting muons’ precession to achieve or lose pace barely.

Saskia Charity, a scientist at Fermilab, said that the “g-factor causes the muon spin to wobble when you put it inside a magnetic field.”

“I like to think about it a bit like when you put too many pieces of paper behind a fridge magnet, you add an extra one in there, it doesn’t feel the force as much and will fall off your fridge,” she mentioned.


“Today is an extraordinary day, long awaited not only by us but by the whole international physics community,” mentioned Graziano Venanzoni, a spokesman for the Muon g-2 experiment and a physicist on the Italian National Institute for Nuclear Physics. “A large amount of credit goes to our young researchers who, with their talent, ideas, and enthusiasm, have allowed us to achieve this incredible result.”
