all those properties, and now we know the mass experimentally. Erm. It would be tragic if the only thing we did, at the large Hadron Collider or anywhere else, was to go on elaborating the verification of the Standard Model. And... The Standard Model is certainly not the end of the story, no-one thinks it is. It has a lot of unexplained features like numerical quantities, ratios of masses, we don't know where they come from. It doesn't include gravitation, which is a big thing not to include. Erm. And we are not, we are happy with it as far as it goes. We desperately want to go beyond it. And erm we may not be able to, in our lifetimes.
693:(The "oscillations" are observed for neutrinos but not quarks because neutrinos are very light, travel very close to the speed of light, so the wave packets of three mass eigenstate neutrinos drift apart very slowly, interfering with each other and resulting in easily detectable distance-dependent probability patterns in neutrino beam from e.g. muon neutrino factory. Whereas quark masses are noticeably different, so interference pattern is lost quickly, and quarks also hadronize (they are not in free flight on a straight path).) 245: 235: 214: 76: 709: 941:
Instead, I spent that time working with my friend Ben Lee trying to find an alternative theory that could account for the experiments. I’m proud to say we failed, as it later turned out that the experiments were wrong. In the end, the issue was settled by a 1978 experiment at SLAC that confirmed the prediction of parity violation in the interaction of electrons with nuclei. After that, I think everyone was convinced that the standard model was correct.
324: 130: 109: 21: 67: 940:
I was confident that the theory was right, but my confidence was partly shaken by data from a number of experiments in 1976 and 1977 that were hard to make sense of within the standard model. In the spring of 1977, I ended up canceling a trip I had planned with my wife and daughter to go to Yosemite.

The YouTube videos do show that Weinberg asserted that he invented the term. They are not unreliable sources and the flag for that should be removed. The question of whether Weinberg's claim belongs in the historical account is another issue. Weinberg was a prominent spokesman who presented topics in
848:
Claims are indeed not facts that is why the extra sentence never said SW came up with the term. But he does appear to claim he did, which is absolutely relevant as far as history of science goes. Again, I'm not advocating to include "SW came up with the term" but rather "SW claims he came up with the

The article currently contains the sentence "The Standard Model includes 12 elementary particles of spin 1⁄2, known as fermions." I'd like to see a similar statement somewhere in the article about how many bosonic elementary particles there are, if counted in the same physics-meaningful way. Thank
829:
Claims are not facts, and lengthy interviews are not very reliable sources. If you know any paper from the 70s (probably) where Weinberg used the term 'SM', it can be mentioned. But right now it's just useless, as anyone, even great physicists, can claim any thing they want. And besides, Weinberg is

but for some reason somebody reverted it. Why? Steven Weinberg is definitely an authority on the subject and I didn't say "SW came up with the term" but rather "SW claims he came up with the term" which is apparently correct, given his claims in the two videos. Shouldn't we have these in the history
931:
I don’t know exactly, but I remember using the name in 1973 during a talk in Aix-en-Provence in France. I wanted to point out to my audience that we physicists had a pretty good picture of elementary particles by then, and we could use this “standard model” as a device for interpreting experiments.
915:
Ha ha ha. Well I wouldn't say that either. But it works, and in an almost boringly repetitive way we keep testing it. The discovery of the Higgs boson a few years ago turned out to just fit what was expected. The Standard Model predicts all of its properties except its mass, and it was found, with
767:
I agree. Updating the current one would be ideal, but it's something I can't do myself. However, I just discovered that there is a talk page for that picture as well, so I just offered an updated version of the image there. I apologise if I should have gone there directly, I'm still new to this...
689:
But the diagrams usually show "electron neutrinos" which are supposedly the result of electron's transformation. It is not. Electron transforms into one of three mass eigenstate neutrinos. When this neutrino is detected through some interaction, it transforms back to either electron, muon, or tau.
752:
Though current diagram may be not ideal, it's still more readable and looks better. Maybe it can be just updated with whatever the consesus would be, rather that substituted? I can follow it, but the previous (current) one are easier for understanding. (I'm not a practicing physicist, though I've
737:
Oh, I see. I never noticed that this representation actually aligns with the order of masses. However, the masses are already explicitly stated in the corresponding fields, so ordering them like that seems a bit redundant. So, we might as well use this degree of freedom to implicitly express the
664:
I also have a minor problem with the current diagram. It shows the charged leptons above the neutrinos. I think it should be vice versa to reflect their order in the corresponding weak isospin doublets. I'm not sure if the current image can easily be modified to fit this because of the grouping
1374:
No, it is wholly inappropriate in every instance on Knowledge to receive editorial objections from other editors, and respond with "I'll be doing it anyway unless someone else stops me". Plus, what does "full formal name" mean? We don't care about formal names, we care about common names. When
690:
But when it is in flight, it's NOT "electron" or "muon" or "tau". If the distance from the source is very large (e.g. billion of light years) and if we'd be able to know when exactly neutrinos are emitted, time of arrival would be usable to determine which mass eugenstate was in flight.

It is completely unintelligible without already knowing everything on it (and even then it is extremely difficult to follow and low quality), and it does not provide anything at all that isn't explained much better in the article/other images already. I am removing it as was already
912:: We have a very good theory of all the particles and forces that we can study in the laboratory which I gave the name "The Standard Model", erm, which seemed to me not excessively immodest, I mean. Biologists have something called the Central Dogma and I was trying to avoid that 1353:
The "Standard model" part of the name "Standard model of particle physics" refers to this general concept of a standard model. This general concept is the main meaning of the term. It is wrong and confusing to have an article about a particle physics theory to have this name.

That's the full formal name of the theory. "Standard model" a shortened term that is used colloquially mainly within the field of particle physics. The title of an encyclopedic article should be the full name. Using the colloquial term as the title is wrong and confusing.

There's a mistake in the "Elementary particles" chart. Under Gauge Bosons, it has the header "Four kinds", but under that header it gives three items numbered 1, 2, and 3. Compare the nearly identical chart, in which there is an item 4, graviton, in the article

In the cited YouTube video, Weinberg makes a number of interesting points relevant possibly to the Introduction of this Knowledge article. Here is the transcript as a basis for further editorial work:

The term "Standard Model" is very general. It can be use and is used to refer to a lot of different things in different contexts. Having this term as the title of this page is confusing to readers.

According to my friend with a PhD in physics, this diagram is correct. My opinion is that it ought to be in the article, since it's perfectly relevant to the subject matter; I am re-adding it.

Evidently graviton was removed in this article since gravitons are not part of the Standard Model, but then there are only three kinds and the chart should be revised accordingly.

While I agree that the image is too busy, or technical for a lead, I think an alternative should have been found by now. It's been over a year, apparently.
1308:"Standard model" is a general term that has a general meaning and is used in a lot of different fields. The following is a list of a just a few examples: 794:
I added a sentence saying Steven Weinberg claims he came up with the term for what we call today the Standard Model and added this: Although according to

There are certainly other ones out there, but when talking about the 'Standard Model', this is the one that's typically being referred to. 1204:

I think if there is an updated version of this table, it would be a terrific replacement for the original lead image.

In the introductory section, where the Standard Model's shortcomings are listed, I noticed the following statement:

Another problem is that in reality, lepton and quark sectors are completely analogous versus weak interactions:
