Talk:Particle identification

I corrected the statement that the particle id identifies eementary particle... it was factually wrong: the particle id can identify kaons and pions for instance which are not elementary particles..

Other than this I think the aim of the article is not really the right one, usually in particle physsics the particle id is defined as the ability to identify a particle from another, while the article seems focused on jet identification. Tatonzolo 07:41, 26 October 2006 (UTC)


 * It's got one line about each of a bunch of different things, and (as you rightly point out!) it's missing stuff on pions and kaons and so on. I'm not sure I see how the approach is wrong...  Your claim is that jet tagging shouldn't be mentioned in the article at all? -- SCZenz 23:25, 26 October 2006 (UTC)


 * no I mean that jet tagging is just another subject, maybe good for another article: I thought as particle identification as just the possibility to recognize signle mesons, baryon or elementary particle: pion/kaon/proton discrimination or pion/muon, or electron/muon. These discriminations are just based on fundamental princicples (like dEdx measure or cherenkov angles for instance), the one mentioned and for jet tagging in particular, they are strongly dependent from what kind of algorithm you use for jet reconstruction.. so they are not detector free... it's just a point to see that... maybe we can split the article in two main section one about jet tagging, (maybe the second one) and one about the single particle id.. what do you think about it?Tatonzolo 07:26, 27 October 2006 (UTC)

The b-tagging section suggests that the tagging of light quarks is simply impossible. It is difficult but one can use a jet charge observable to somewhat distinguish between up-type quark, down-type quark, and gluon jets (for instance, see http://arxiv.org/abs/1209.2421). I think it should be stated as difficult but that some observables, even after reconstruction in the detector, can help identify the light jet flavor. — Preceding unsigned comment added by 80.218.252.44 (talk) 00:30, 15 September 2012 (UTC)
