The 2023 result from the Muon g-2 experiment at Fermilab was unveiled and discussed in a special seminar on August 10, 2023. The experimental result was presented by James Mott, Fermilab physicist and collaborator on the Muon g-2 experiment.
The Muon g-2 experiment searches for telltale signs of new particles and forces by examining the muon’s interaction with a surrounding magnetic field. By precisely determining the magnetic moment of the muon and comparing with similarly exact theoretical predictions, the experiment is sensitive to new physics lurking in the subatomic quantum fluctuations surrounding the muon. The highly anticipated result from Fermilab’s Muon g-2 experiment strengthens the experiment’s 2021 result and doubles its precision. It is also the world's most precise measurement of the anomalous magnetic moment of the muon.

So many times we experimentalists had to struggle for years to measure something theorists had predicted with great precision many years before. Now is the theorists' turn to struggle to match the precision of this very fine experimental measurement !

This was a fantastic presentation. Mr Mott made it as simple as possible but not simpler. I didn't know anything about this domain but was able to follow along

Halving the uncertainty is an amazing feat. This pretty much confirms there is new physics to be found. Great work to the team of scientists at Fermilab!

@ellielikesmath 9 ай бұрын

pretty sure it does not confirm that. pretty sure you do not know what you are talking about.

@garythepencil my first sentence is not leading the following sentence. I'm no physicist but I can follow along. If I'm wrong, correct me instead of just telling me I don't know what I'm talking about.

I can feel their excitement! From childhood I was trying to catch μ, and they also seem to be looking for μ too! So I'm not surprised by their dedication!

Would love to have Dr. Lincoln present the findings to those of us interested in physics, but have come to it later in life and our educational careers. Hope he is well and working on a new content. My best and many thanks.

The experimenters did a fantastic job on this. Wow, amazing results. The standard model calcs seem rock solid too with two methods used to get the number. Where is the difference? New physics? I'd put my money on "we missed something" over new physics but... it could be! Maybe finally we have a path to break the standard model.

"I'd put my money on "we missed something" over new physics" If we missed something when enumerating physics, the thing we missed would be new physics

@@viliml2763 Maybe it is new physics. A new interaction or a new particle. But it could also come down to math. Each small interaction is given a strength. Small errors add up when you start talking about lage numbers of extemely complicated events deep into the QED tree. If the calculations errors (remember there are error bars in each) were not as accurate as we thought, then you will be off on your overall QED interaction calculations. It will get worse as we add more interactions, not better. I am not saying that is what this is, smarter folks than me are working it. But the SM has been turning out to be right why would I expect it to be wrong here?. I would still bet on a mistake, not new physics. Math still has as much a say as any "new physics" we dream up.

@@jppagetooI think that too. I think it's time for physicists to consider non perturbative methods, which means rewriting QFT in a way that's mathematically consistent, instead of looking at new particles. We probably found them all

This is an amazing scientic achievement. Congrats to everyone involved, it must have been extremely challenging. I'll leave a constructive criticism, though. Please go online and compare the video/audio quality of this video, against some nobody doing some nothing. They are miles ahead, guys! This is bearly watchable, I'm sorry. Please hire an influencer and up the quality of your communication. That's the only way to get fresh blood into the field and recover the much needed credibility of this most successful intellectual enterprise of our species, that is science.

5 sigma, huh... it's official, then. We've got a problem in our hands! And the ball is now on the theorists' roof...

@alexfy7401 10 ай бұрын

Yeah I had to look up the sigma required by physicists. It should be 5 sigma. Maybe it doesn’t apply for this experiment, I guess they’re aiming for 6.

There's an endless host of manmade subatomic particles, all brought into existence and made to do unbelievable things. They exist routinely in pairs, with a matter-antimatter identity. They might have profound uses as "biodegradable" substances that do their job, and get out of your body. All of the limitless possibilities of particles have a limited half-life. Which doesn't detract from their value. Including our future in interstellar space travel to other worlds. ✝️🌠

Why not translate this into intelligible English? Very poor rendering of the caption text as well, eg: 2,018 for the year 2018. I will assume more mistakes were made and none of this is worth watching.
