The results of the Muon g-2 experiment show that elementary particles called muons behave in ways that standard models of particle physics would not expect.
Fermilab, the American particle accelerator, is launched The first results of the muon g-2 trial. These results highlight the anomalous behavior of elementary particles called muons. The muon is a heavier cousin of the electron and is expected to have a value of 2 for its magnetic moment, which is called “g”.
Now, muons are not alone in the universe. It is an integral part of the ocean where particles appear and disappear all the time due to quantum effects. Therefore, its g value is changed by its interaction with this short-lived excitation.
The Standard Particle Physics Model calculates this correction, called the anomalous magnetic moment, with great precision.
The muon g-2 experiment measured the extent of the anomaly, and on Wednesday, Fermilab announced that “g” had deviated from the amount predicted by the Standard Model. This means that while the value calculated in the Standard Model is approximately 2.00233183620, the experimental results show a value of 2.00233184122.

They measured “g” with an accuracy of about 4.2 sigma, when combined with the results of a 20 year old experiment, which means that the probability that this is due to statistical fluctuation is about 1 in 40,000. This gets the physicist up and taking notes, but it’s not that important because it’s Enough to form blots – they need 5 sigma significance.
Factor g
Muons are also known as fatty electrons. It was produced in abundance in the Fermilab experiment and occurs naturally in the rain of cosmic rays. Like electrons, muons have a magnetic moment because they are placed in a magnetic field, they spin and spin, or they sway a little, like the top axis. Its internal magnetic moment, the factor g, determines the extent of this oscillation.
As the muon rotates, it also interacts with the surrounding environment, which is made up of short-lived particles that appear in and out of space.
The implications of this difference for the muon g factor can be significant. The Standard Model is assumed to contain the effects of all known particles and forces at the particle level. Thus, the paradox of this model implies the existence of new particles, and their interactions with known particles will expand the panel of particle physics. These new particles may be the dark matter particles that people have been looking for for a long time. This reaction makes a correction to the factor g and this affects the muon movement.
If the measured factor g differs from the value calculated by the Standard Model, it may indicate the presence of new particles in the environment not described by the Standard Model. These observations, together with the recently observed anomaly in B degradation at CERN suggest that a new, as yet unobserved, particle effect is being seen.
Note of caution
There are also calculations made by a group of scientists which are featured on Temperate nature Which uses the same standard form to explain this difference. But this alleged model has major flaws and needs more evidence.
