@_thegeoff aw I always found truth and beauty to be supremely weird. Like, the kind of names people would come up with if they were on drugs. (Which very well may have been the case, to be fair)
Strange and charm are also pretty weird but I guess I've become acclimated to them since there are no viable alternatives....
@diazona @_thegeoff "Strange" is at least understandable given the history.

@skyglowberlin @diazona I was a first year physics undergrad when the last quark discovery was announced. Much excitement through the department. You may say a "top" day...?
Thank you, I'll be here all weak. -
In case you missed it, new particle just dropped. The LHC has confirmed (and in ridiculous accuracy) the existence of a heavier version of the proton.
A proton is made of 3 quarks, up/up/down. This new particle is made of charm/charm/down, where the charm quark is basically the same as the up, just heavier.
So not groundbreaking like finding supersymmetric particles, but still cool. Further confirmation that the standard model of particle physics is reasonable.
https://home.cern/news/news/physics/lhcb-collaboration-discovers-new-proton-particle@_thegeoff Whoa!
-
@diazona But you're fine with up and down? On the canvas of the Entire Universe?!
There's a bit of me that respects them not being called Q+2/3P1 etc (yeah, looking at you, gauge theories). But it does imply things in the general popsci field. On the whole I say keep the weird hippy names. And yes, very probably cos 1960s drugs.
@_thegeoff
yeahAll things considered, I prefer physics being weird to the opposite

@skyglowberlin @_thegeoff Oh yeah that's a good point. That's probably part of why I don't mind "strange" and "charm", too: the names have little historical lessons about their discoveries embedded in them. "Truth" and "beauty" on the other hand always felt completely arbitrary to me.

@diazona @_thegeoff I remember "strange particles", but I don't remember ever hearing an explanation for where "charm" came from.
I just looked it up on Wikipedia, and
Since up and down are also arbitrary, "strange" is the only name of the six that I think is reasonable
-
For non physics types, the quark names "up, down, charm, strange, top and bottom" are completely arbitrary and mean nothing, they're just placeholder names. Which is annoying, cos top and bottom were originally truth and beauty, which I prefer.
The also come in colours, and are far, far, far smaller than the wavelength of visible light. Again, an arbitrary name.
Lesson to all you physics coders, dumb variable names can stick if you're unlucky. Don't predict the "YourMomHadron".@_thegeoff I don't think colours are _entirely_ arbitrary though: afaik they are related to SU(3) irreps, so there are 3 basis states, and we have 3 coloured sensors in eyes, so...
But yeah, it's just that 3 equals 3 and nothing deeper

https://home.cern/news/news/physics/lhcb-collaboration-discovers-new-proton-particle@_thegeoff I'm sorry but since it does not yet have an official name; we'll be referring to it as the "Chonk Proton" for now.

@laprice @_thegeoff Shortened to 'chonkon' of course.

https://home.cern/news/news/physics/lhcb-collaboration-discovers-new-proton-particle@_thegeoff This is really cool.

@kimlockhartga Yup. A lot of the stuff coming out of the LHC post-Higgs tends to fail to ignite popular curiosity, even though it's essentially part of the same model. But this being directly relatable to high school physics gives brownie points!

- CERN is a TLD
- this is not a shitpost and charm quarks are real. -

https://home.cern/news/news/physics/lhcb-collaboration-discovers-new-proton-particleWhat would be the spin? (In case you're wondering, I am an NMR spectroscopist
) -

Another particle has been found!
In fact the Large Hadron Collider has found 80 new particles in addition to the Higgs boson. All of these 80 are 'hadrons', collections of quarks and/or antiquarks held together by the strong force. We *expect* there to be bucket loads of these, since there are 6 kinds of quarks and many ways for them to stick together. By now, studying these is more like chemistry - the working out of possibilities offered by a more or less understood theory - than truly groundbreaking fundamental physics.
Still, particles are cool. Here's a list of the 80 hadrons found by the Large Hadron Collider:
The most exciting are those made of 4 or 5 quarks, or 2 quarks and 2 antiquarks. Most hadrons are less fancy! Most are made of either 3 quarks (these are called 'baryons'), 3 antiquarks ('antibaryons'), or a quark and an antiquark ('mesons'). The newly discovered 'heavy proton' is a baryon made of two charm quarks and a down quark.
