Talk:Timeline of particle discoveries

message: Regarding the question of whether the Higgs should be on this list, well... No, it shouldn't.  But it would then be the only Standard Model particle that wasn't, so I thought it made sense to have it mentioned in some way, and I put it on the timeline where it would fit.  So I think it's ok as is, but if there are other opinions..?
Just found this page... in my opinon, a list of discoveries should not include speculation about the future and should just stick to history. So I think the Higgs should be removed from the list.  Bodhitha 17:58, 11 October 2006 (UTC)

replies: text: Sorry what I meant was ... when can a particle be said to have been "discovered"? Examples: "1858 - Cathode rays produced by Julius Plücker (later identified as electrons)" ... but ... "1911 - Atomic nucleus identified by Ernest Rutherford, based on scattering observed by Hans Geiger and Ernest Marsden". So one is dated on cathode rays being produced whereas the other is dated on atomic nuclei being identified two quite different parts of the discovery process. Abtract 00:31, 20 January 2007 (UTC)
thread_title: Definition of "discovery"

message: Why doesn't that page include a more complete list of the discoveries of mesons and baryons?
The fact that they are not elementary particles should not preclude their listing, in my opinion. Dauto (talk) 02:56, 19 February 2009 (UTC)
thread_title:  hyperons 

message: Antihydrogen is distinguished from an antiproton by the fact it has a bound positron.  I think the STAR result just found an anti-alpha-particle or anti-He4 nucleus.  Can someone check and fix the entry (to He4 anti-nucleus) if necessary? 130.246.132.178 (talk) 14:42, 21 July 2011 (UTC)
thread_title:  Antihelium a nucleus or atom? 

message: These particles should not be included just because they have been discovered recently.  Their discoveries have not been significant or unprecedented in any way, except to demonstrate the performance of the detectors used to discover them.  These particles do not fulfill any of the three criteria listed at the top of the page. Aidansean (talk) 00:19, 12 June 2012 (UTC)
replies: text: I agree. I understand these are very significant discoveries for the teams who run these experiments, and they are undoubtedly the result of years of hard work. But they have no specific historical significance, and do not revolutionize our understanding of the natural world in any way. I'm going to remove them from the list in a few weeks unless someone offers a reason for them to stay. JanJaeken (talk) 11:07, 8 May 2013 (UTC)
replies: text: I have removed the entries from the list. I'm still on the fence about anti-He4. Being the first particle to be detected at STAR is insufficient reason for inclusion, yet it is the first signal of an anti-alpha particle. The importance of the alpha could make this discovery worthwhile to mention, but I'm not certain. If anything, if it is to stay, it needs a proper citation. JanJaeken (talk) 08:56, 1 July 2013 (UTC)
thread_title:  Chi-b and Xi-b 

message: Does this page need to be updated for the new Xi baryons?  Bubba73 You talkin' to me? 04:29, 20 November 2014 (UTC)
thread_title:  Update for new Xi particles? 

message: The timeline of the discovery of unambiguously exotic hadrons (particularly with heavy quarks) is a bit muddy, with later measurements often confirming the exotic composition of previously discovered particles. That being said, I think the X(3872), Z(4430), Pc(4380) and Pc(4450) probably deserve to be included as the first exotic mesons and exotic baryons.
