Talk:DØ experiment

Disposition of Experiment?

Is the detector still in the beam line? Any disassembly pictures? — Preceding unsigned comment added by 76.136.223.193 (talk) 21:07, 20 January 2024 (UTC)

Information Needed

Do we really need one of these headings every other line, especially when there's entirely blank subheadings? Seems superfluous to me. --Anonymous —Preceding unsigned comment added by 71.5.23.98 (talk) 03:51, 11 September 2008 (UTC)

Article title

I proposed this be moved to D0 experiment, rather than the current title. I would never have looked for it here. -- SCZenz 06:36, 27 January 2006 (UTC)

Thanks for this suggestion -- makes sense to me. Burair 06:00, 28 January 2006 (UTC)

Agreed. Do we move to DØ experiment or D0 experiment?Headbomb {^ταλκ_{κοντριβς} – WP Physics} 05:06, 3 April 2009 (UTC)

If the Ø in DØ is supposed to be a (slashed) zero, I believe using 0 would be most correct. The letter Ø is not a zero, and the empty set symbol ∅ isn't either. (Trivia sidenote: The Norwegian interjection "DØ!" means "DIE!" in English.) - Soulkeeper (talk) 16:06, 2 October 2011 (UTC)

Yes, it should be 0̸, a slashed zero. A Skandinavian Ø is just wrong. --RokerHRO (talk) 20:05, 8 November 2021 (UTC)

Strange symbol

What is the symbol Ø? A cutted zero? Or an empty set symbol? Or a radius symbol (something to do with the ring)?... -- NIC1138 (talk) 03:13, 24 March 2008 (UTC)

It's a zero. The Tevatron is divided into six sections A-F, and there are numbered stations within each section. The detector is located at D0.Mjamja (talk) 03:03, 3 April 2008 (UTC)

"0" is a zero. "Ø" is a capital letter O with stroke. "∅" is the empty set. sneakums (talk) 22:47, 19 March 2009 (UTC)

Agreed. See my note above (in the "Article title" section). "DØ" is obviously incorrect. - Soulkeeper (talk) 16:08, 2 October 2011 (UTC)

Premier?

whether it's true or not, the second sentence seems pretty pov.Toyokuni3 (talk) 04:22, 25 May 2008 (UTC)

DØ experiment → D0 experiment – The Ø used presently is a substitute for a slashed zero. Unicode doesn't have a character for slashed zero. Using an Ø instead of a zero is inaccurate because Ø is an alphabetic letter for a vowel and not a numerical digit, and also because Ø looks slightly different from a slashed zero anyway (see article about slashed zero). The empty set symbol ∅ also looks roughly similar to a slashed zero, but that would also be inaccurate, both in meaning and in appearance. The name "D0" keeps the intended meaning (the letter D and the number zero) at the cost of an inexact visual similarity. See also previous discussions on the talk page. Soulkeeper (talk) 16:30, 2 October 2011 (UTC)

Whatever it might be a substitute for is not for us to say. The official web site uses "Ø", so that's what we should use unless something else is more widely used in reliable sources. Powers ^T 19:58, 2 October 2011 (UTC)

We can make a very educated guess: This picture, used in the article, clearly shows a slashed zero. The d0 website uses all three terms, and in it's glossary it uses D0. Also, from the Introduction section: "The name of our detector is based on the naming scheme of the Tevatron Collider (schematic view of the Tevatron), which is divided into 6 sections. The DØ - Detector is located in section D, precisely at the point called 'D0', whereas the CDF - Detector for example can be found in section B (at the point 'B0'). The main injector is connected to the Tevatron in section F (at the point 'F0')." - Soulkeeper (talk) 15:36, 3 October 2011 (UTC)

• Support. What Powers refers to above as the "official web site" bows to the practicalities in naming its own site: "www-d0.fnal.gov". Try "www-dØ.fnal.gov". It fails. The site also bows to convenience with text such as this on its front page: "July 2011 DZero Higgs Search Results".

There are similar advisory restrictions in Wikipedia titles (see Wikipedia:Title#Special characters). The choice of "Ø" at the "official" site is a stylistic choice, not a semantically significant one. Wikipedia has its own policies, and its own style guidelines that it imposes – just as all other publishers do.

Many organizations have to make concessions to technical limitations in choosing domain names; in no way should those concessions be seen as definitive. As such, it's original research to determine that they really mean the "Ø" to be a "0" and change their branding -- in that respect, it's quite different from other MOS:TM-based rules. Powers ^T 11:59, 3 October 2011 (UTC)

The alternative spelling "DZero" indicates that they really mean the "Ø" to be a "0". If they also had used the spelling DØ, it would be ambiguous, but they don't. - Soulkeeper (talk) 16:46, 3 October 2011 (UTC)

Not necessarily. Maybe it works the other way around -- maybe "Zero" is used as an approximation of "Ø" since there's no good English-language word for the symbol. Powers ^T 11:29, 4 October 2011 (UTC)

From the article Ø: "The name of this letter is the same as the sound it represents (see usage). Though not its native name, among English-speaking typographers the symbol may be called a "slashed o" or "o with stroke"." So it's clearly a letter, not a number, and I personally doubt that particle physicists would be that sloppy with their symbols. But anyway, what do you think about the suggestion from 70.24.246.153, to move the article to DZero experiment instead, then? - Soulkeeper (talk) 18:10, 5 October 2011 (UTC)

• Oppose use DZero experiment instead. D∅ experiment should redirect to it. 70.24.246.153 (talk) 13:27, 3 October 2011 (UTC)
  • I find DZero acceptable also; At least it's not flat-out wrong. :) - Soulkeeper (talk) 15:36, 3 October 2011 (UTC)
• Comment "O" is frequently used in place of "0" in text and common speech so Ø is not so different. Perhaps a MontyPythoner subtitled the thing? 70.24.246.153 (talk) 13:29, 3 October 2011 (UTC)
• Support; I'm convinced by the sources below. Powers ^T 13:24, 6 October 2011 (UTC)

I couldn't find that many using DZero or D-Zero, but there are some. - Soulkeeper (talk) 15:47, 3 October 2011 (UTC)
