Measuring Muon g-2

Here we look at the principles behind the recent experimental determination of the anomalous magnetic moment of the muon from the Fermilab Muon g-2 Experiment. We look at how an antimuon interacts with an applied magnetic field and see how parity-violating decays of the muon allow the determination of the spin direction. We see how these are used to determine g-2 of the muon.

What is g-2 of the Muon? Part I:

Fermilab Apr. 7 seminar:

[MrBendybruce]

I just discovered this channel. How the hell does it not have hundreds of thousands of subs?!? Channels like this, that focus purely on helping laypersons (like myself) gain a deeper understanding of the mechanics underlying current scientific knowledge, is very much appreciated.

[nasserzir]

I must say. She is just awesome
As a teacher, I try to write something about it.
after watching several videos from others, I think this is the best.
She explains it calmly. uses simple examples for difficult topics. takes us step by step out of the dark jungle to clarity.
When I start writing for my students, questions will arise. Therefore I will be happy if I can to send you such questions

[Markoul]

Congratulations! You explain and present it even better than latest the g - 2 seminars. This is a very serious and excellent physics channel.

I think that before we start assuming new particles, we'd first need to check
whether or not the abberant muon wobble, (which took me ages to find out what it is, my time)
may be the result of sympathetic electromagnetic vibration.

What I mean by this, is that current travelling through a wire pops in electrons one side of an atom,
where the other side of that atom would have to release the added electron.
This in turn creates a very minute electromagnetic wave front, which then happens all through the wire.
Decillions (arbitrary large number) of atoms getting an electron added, while relaesing one as result
of the electron pressure on the opposing end, each creating their own electromagnetic wavefront,
and combined resulting in a powerful electromagnetic field.


But.

This in turn means that there's an extremely high, possibly even uneven, frequency attached
to this field, which then in turn may be either sympathetic or asympathetic or neither.

Let's say the muon's sympathetic frequency is like 4 ghz (arbitrary number), and the frequency
of the electromagnetic field would be any whole number multiplier of that, it would receive
sympathy, or possibly only a short near sympathy which then happens on a freqency
of it's own.

I'd have that muon test redone with varying voltages, possibly even alternate currented,
counterfielded and minute time magnetic field tested and maybe even alternate cored,
alternate coil length and thicknessed.

Who knows, if that changes the wobble, than the wobble can be controlled at least,
which makes it more useful for testing purposes alone.
(Or possibly a new timing method that can reach peta/exa Herz.)

17:44 Muons are not supposed to exist (at least for long),
but as a result, the energy they represent may decrease over time as well.
Once a threshold energy is reached they decay, but in the cyclotron
they have energy added through their speed, much like photons.

Photons, despite being very different particles, don't lose speed but lose energy,
when subjected to a gravity field, and can only escape a black hole through
burning off energy. So, this phenomenon may change the characteristic
of a particle, mere loss of energy.

Can this be what lengthens the time till they decay as well, but also
if they'd have more speed added like in a really large accelerator like Bern LHC,
would they then stay existent in undecayed state for longer still ?

Would be interesting to know.
