Hadron overhaul[edit]

Please give input at Talk:Hadron#Hadron overhaul. Thanks. Headbomb {ταλκκοντριβς – WP Physics} 01:58, 24 January 2010 (UTC)

Xi-0 Lifetime[edit]

Should it be noted here that the Xi-0 Baryon has the longest mean lifetime of all non-Nucleon Baryons? If not, am I wrong about this? Thanks. —Preceding unsigned comment added by (talk) 20:24, 2 July 2010 (UTC)


I added a Xi sub b 0* (usb) to the baryon list, as it was discovered by CMS collab at CERN, and published results on 2012-04-27 ( List_of_baryons#jp_.3D_3.E2.81.842.2B_baryons. Could some one also add it here? -- (talk) 01:49, 28 April 2012 (UTC)

Asterisks in JP[edit]

There are numerous asterisks in the JP column. What do they signify? Solo Owl 00:27, 18 November 2014 (UTC)

I had the same question about the asterisks on the isospin column. I don't see that the text explains this, but am guessing it has to do with varying isospin excitations. Wild guess. — Preceding unsigned comment added by (talk) 20:45, 28 December 2016 (UTC)

underscores or subscripts?[edit]

Don't the underscores in Xi_b'- and Xi_b*- represent subscripts? Bubba73 You talkin' to me? 04:25, 20 November 2014 (UTC)

Merge Ξcc++[edit]

Generally on English Wikipedia, hadrons are grouped into articles about their main symbol. An exception being strange B meson, but that has been very well studied to the point where there's enough material for a separate article from B meson. The Ξcc++ baryon has only been observed in one decay mode in one paper (so far). I think it's far from being noteworthy enough for a separate article. — dukwon (talk) (contribs) 10:00, 7 September 2017 (UTC)

Really, these articles should all be split. It's how I organized them way back when for convenience, but it was a mistake I made when I thought these were related particles. Headbomb {t · c · p · b} 10:22, 7 September 2017 (UTC)
I agree that organisation by main symbol is not ideal, but I don't think there should be separate articles for every individual state. It's getting a bit silly with the exotic mesons (X(3872), Zc(3900), Z(4430), Y(4140)). If they're going to be re-organised, I suggest mimicking the PDG: [1]. — dukwon (talk) (contribs) 12:19, 7 September 2017 (UTC)
Mesons in general, are a fucking mess. Even non-exotic ones. I should know, I did a thesis on [originally] hadron nomenclatures, and mesons states were way too complicated to address. I managed to come up with a [IMO] much simpler naming scheme for baryons, but mesons were sadly too muddy to streamline. Headbomb {t · c · p · b} 12:25, 7 September 2017 (UTC)
