What is the Muon g-2 discovery?

Muon g-2 (pronounced “gee minus two”) is a particle physics experiment at Fermilab to measure the anomalous magnetic dipole moment of a muon to a precision of 0.14 ppm, which will be a sensitive test of the Standard Model. It might also provide evidence of the existence of entirely new particles.

What is the Muon g-2 experiment and how are magnets used in this experiment?

The Muon g-2 experiment sends a beam of muons into a ring of magnets, where they circulate thousands of times at nearly the speed of light. Detectors lining the ring allow scientists to determine how fast the muons are precessing.

What did Fermilab discover?

bottom quark
Fermilab discovers bottom quark In 1977, an experiment led by physicist and Nobel laureate Leon Lederman at Fermilab provided the first evidence for the existence of the bottom quark. It was observed as part of a quark-antiquark pair known as the Upsilon meson, which is 10 times more massive than a proton.

What can wobbling muons tell us 1st result G-2?

Special event sharing the first result from the Muon g-2 experiment! The results show fundamental particles called muons behaving in a way that is not predicted by our best theoretical model of the subatomic world, the Standard Model of particle physics.

Is there a fifth fundamental force?

Although the researchers found no signs of a fifth force, they did determine a new limit, 10 times stricter than before, on how strong such a force could be. The NIST team believes that their innovative experimental setup will allow them to make even more precise measurements in the future.

Is Fermilab open to the public?

Fermilab’s site is open to the public every day of the week from 8 a.m. to 6 p.m. from November through March and from 8 a.m. to 8 p.m. the rest of the year. A map of Fermilab’s public areas is available online.

Is it safe to live near Fermilab?

Q: Does the tritium at Fermilab constitute a health risk to employees or neighbors? A: No. All tritium levels found on site are well below any federal health and environmental standards. High doses of tritium over a sustained period have been shown to increase the risk of cancer.

Who pays for Fermilab?

Batavia, Ill. —In the first installment of funding from the U.S. Department of Energy’s Office of Science under President Obama’s American Recovery and Reinvestment Act, DOE’s Fermi National Accelerator Laboratory will receive $34.9 million.

How did the muon experiment confirm the theory of relativity?

Evidence for time dilation as predicted by the special theory of relativity came in experiments that dealt with elementary particles such as muons. Indeed such experiments confirmed the fact that when an elementary particle travels with a very high velocity, its lifetime increases.
