Finding From Particle Research Could Break Known Laws of Physics

Meanwhile, in 2020 a gaggle of 170 consultants referred to as the Muon g-2 Theory Initiative revealed a new consensus value of the theoretical value of muon’s magnetic moment, primarily based on three years of workshops and calculations utilizing the Standard Model. That reply bolstered the unique discrepancy reported by Brookhaven.

Reached by telephone on Monday, Aida X. El-Khardra, a physicist on the University of Illinois and a co-chair of the Muon g-2 Theory Initiative, stated she didn’t know the end result that Fermilab can be asserting two days later — and he or she didn’t need to, lest she be tempted to fudge in a lecture scheduled simply earlier than the official unveiling on Wednesday.

“I have not had the feeling of sitting on hot coals before,” Dr. El-Khadra stated. “We’ve been waiting for this for a long time.”

On the day of the Fermilab announcement one other group, utilizing a special method referred to as a lattice calculation to compute the muon’s magnetic second, concluded that there was no discrepancy between the Brookhaven measurement and the Standard Model.

“Yes, we claim that there is no discrepancy between the Standard Model and the Brookhaven result, no new physics,” stated Zoltan Fodor of Pennsylvania State University, one of the authors of a report published in Nature on Wednesday.

Dr. El-Khadra, who was accustomed to that work, known as it an “amazing calculation, but not conclusive.” She famous that the computations concerned have been horrendously difficult, having to account for all doable ways in which a muon might work together with the universe, and requiring 1000’s of particular person sub-calculations and a whole lot of hours of supercomputer time.

These lattice calculations, she stated, wanted to be checked in opposition to unbiased outcomes from different teams to remove the chance of systematic errors. For now, the Theory Initiative’s calculation stays the usual by which the measurements shall be in contrast.
