Researchers are finding that the wobble of the muon – a cousin heavyweight to the electron – is not quite right, and this points towards a new physics.
Nearly 20 Years after Brookhaven Particle Accelerator researchers in New York provided the first evidence AnomalyHundreds of scientists are working with the Muon g-2 Collaboration Just announcedLatest measurement of muon’s movement in electromagnetic field.
The new analysis, based on data from the US Department of Energy Fermi National Accelerator Laboratory confirms that there is a difference of 116 592 045 x 10.-11 .
This is a very small number. This could be the start of some major discoveries. It is comparable to measuring the distance between two people who live on opposite sides of America and only being off by a few meters.
“This measurement is a remarkable experimental achievement,” The following is a list of words that begin with the word “you”Peter Winter, a physicist from the Argonne national Laboratory in Illinois. “Getting systematic uncertainty down to such a level is an important achievement and something we did not expect to achieve this soon.”
Muons are only alive for a few microseconds on average. In that short time, their bodies behave like electrons. They spin back and forth as the currents of electromagnetic force push against their torsos. Magnetic Moment.
Scientists know how muons are supposed to move in an electromagnetism field. They even have a letter describing this motion – g, for gyromagnetic ratio.
Theoretically, on a dancefloor with only the electromagnetism beat and a moving muon, each gyration can be predicted. This gives g an absolute value of 2.
The quantum dance floor is chaotic, with virtual particles hovering on the edge. The muon is pushed and tripped by the blur of objects in subtle ways, causing its boogaloo dance to be thrown off.
They suggest that g should be slightly greater than 2. If you subtract 2 from g, it should be a clear sign that all of the quantum jostling is taking place.
According to the book, all quantum gatecrashers and their signature moves should be included within the Standard Model. We can add up these effects and take them into consideration when predicting the muon’s true movements using a single numerical value.
The number that was found by experimenters at Brookhaven in the early 1990s isn’t the same as what they found 20 years later. Researchers found that the number is not what they discovered using Fermilab equipmentIn a series of collisions that took place in 2018.
In particle physics, a mismatch between results and expectations is usually due to one of three factors. This could be a statistical mistake, an experiment flaw, or even a theoretical gap.
Of those, the third possibility is the ultimate prize – a hole in the Standard Model that yearns to be plugged.
Given phenomena like dark energyYou can also find out more about the following: dark matterIf the Standard Model cannot be used to explain a phenomenon, then we suspect it has some serious problems.
The Muon g-2 Collaboration confirmed g-2 based on several runs of Fermilab’s particle accelerators in 2019 and 2020. We can now be twice as sure of the existence and force of new particles.
In the coming years, this collaboration will combine past experiments with more recent data in order to build a stronger case that could meet high standards of certainty, and change physics for ever.
