Inaccurate information[edit]

The first image on the page INCORRECTLY denotes the quark structure of a proton. The gluon fields binding the the three quarks together should not shown as connecting one quark to another and forming a triangular shape; rather, the gluon fields should be originating from the direct center of the image and extending outward to the quarks to form a Y-like shape.

I do not think so. See asymptotic freedom. Incnis Mrsi (talk) 05:21, 6 July 2013 (UTC)

Incnis: citing another Wiki article is no justification whatsoever. I have just watched a YouTube video which also explicitly makes the claim that the diagram is wrong, and the person making this claim is, according to the video, Professor Derek Leinweber of Univ. of Adelaide. This directly and explicitly discusses that diagram and says (3 min 30 second into video) that we now know that it is wrong. The diagram needs to be fixed or removed. (talk) 20:48, 29 January 2014 (UTC)

Are sand–PVC models, some speaking faces, and their strangely distorted speech (something like “We know that all picture is totally wrong now. Even if… blah-blah… would see quark tubes around… blah-blah-blah-blah… more than three quarks…”) all that you can present? Give a citation, please, exactly on the question of Y-shape vs triangle. Possibly from the same Derek Leinweber, but as a legible text. Incnis Mrsi (talk) 12:53, 30 January 2014 (UTC)
The video has a link to the man's website in the description, which itself links back to the video, here: On that page is a link to another page, here: which includes a gif showing the Y-shaped flux tubes of three protons of different colours, here: Would it be possible to just use that gif in the wiki article, actually?

I mean, if you really wanted to be accurrate, instead of wavy lines infinitely many quarks and gluons should be drawn. But when you get down to that level of scale any diagram will be inaccurate in some way or another (how would you represent uncertainty, for instance). The one that is currently there works just fine in getting the general point across. ArchPope Sextus VI (talk) 01:48, 15 January 2015 (UTC)

Magnetic shielding correction not in Infobox template[edit]

To Krebs49, who attempted today to add the magnetic shielding correction value to the infobox and noted in his edit summary that the added value does not appear: I believe the problem is that the infobox is generated using Template:Infobox particle and can only show the parameters listed there. So you could either (1) edit the template to include Magnetic shielding correction (and carefully check that this action does not otherwise affect either this Proton article or the articles for other particles), or (2) leave the infobox alone and put the magnetic shielding correction into the text somewhere.

Inaccurate illustration[edit]

The three-balls-held-together-with-springs illustration is, apparently, an oversimplified model of what is inside a proton, which has been outdated since the 1970's. However, a more accurate model would be, apparently, quite complex-- see this illustration: [[File:MyProton|thumbnail|Prof Matt Strassler's illustration of a proton - complex]] and the article from which it comes: I suggest that we put both the simplified, iconic image, and the less-simplified image, suitably captioned.

I don't know if Matt Strassler approves his image for use on Wikipedia or not. Dc3 (talk) 19:28, 4 June 2014 (UTC)

I do not see any point in making the figure more complicated by trying to depict the sea quarks. I think it is still completely valid to say that the proton is made of three (valence) quarks. The "sea quarks" arise from the strong interaction itself, which is depicted with the wavy lines. In a sense, these waves include the sea quarks. If one goes down the path of depicting the sea quarks, why not also the virtual photons, electrons, W bosons, etc. The figure becomes very confusing. (talk) 10:21, 16 March 2015 (UTC)

Synchronize with the neutron article[edit]

I've been poking at the article for neutron of late, with occasional visits to this page. The two articles (and likely others) should have a degree of similarity about them, seems to me. The History section on this article is rather far down in the article, whereas it is at top in the neutron article. I tend to think the history section should be toward the top since this section also serves as an introduction to the topic. In any case, a certain uniformity in article design would likely be helpful. Bdushaw (talk) 03:19, 15 September 2014 (UTC)

I consider that a synchronization of this article with electron, beside that with neutron, is useful and recommended.-- (talk) 11:38, 19 September 2014 (UTC)

Radius values Inconsistency[edit]

The radius given in the body of the text is given as 0.84–0.87 fm, whereas in the top-right table it is given as 0.8775(51) fm. I understand that the former one is due to a recent discovery of a different radius and the top-right table is based on a table published prior to that study, but it will be confusing to readers. A more recent data table for the proton (2014), from the particle data group rather than CODATA, gives both values: I suggest doing the same in the top-right box, using this as a reference, and maybe add some details on the controversy to the body of the text. MostlyForgettable (talk) 21:23, 26 March 2015 (UTC)

What controversy? You mean discrepancy?-- (talk) 19:03, 7 November 2015 (UTC)
What's the difference? (talk) 04:08, 6 October 2016 (UTC)

Measurement details[edit]

I see above that values of the proton radius are mentioned. I think it would be useful also that details of measuring methods and their principles be inserted in article.-- (talk) 23:52, 30 December 2015 (UTC)

I understand that scattering data are used to determine the radius of proton. Is it a direct measurement or scattering data are introduced in a formula?-- (talk) 00:58, 31 December 2015 (UTC)

I believe that the formula you asked about was inserted into the article, but it seems insufficiently melded with the surrounding text. I don't know enough QFT to understand how these form factors are useful. Should they be here, or in the main page on the proton radius puzzle? If they should be here, can you improve it? Thanks, (talk) 04:08, 6 October 2016 (UTC)

Proton cation in compounds[edit]

The occurence/existence of any compounds which contain bare proton as cation would be a useful addition to article. Is there any awareness of sources with such compounds described?-- (talk) 11:20, 8 November 2015 (UTC)

Classical radius of proton[edit]

The article says that a quantity called classical radius of a charged particle is convenient to be defined. Can also proton have a classical radius defined for for it?-- (talk) 13:51, 12 February 2016 (UTC)
