According to the history this page was moved to Tau (particle) and now we're moving it back again?

- Yes, most of the articles linking to this particle do so via the Tauon redirect page. I've adjusted the remaining few articles so that all articles now point to Tauon. Check the template on Tau (particle) article - it refers to Tauon (which is a redirect to Tau (particle) and not Tau (particle) - so it remains linked when it should be bold. If we can move Tau (particle) to Tauon then all the redirects go away; and the template will finally work correctly. I'd suggest that the original move was a mistake - possibly by a person whose national article for this particle is Tau rather than Tauon. As such, the English page has probably laboured under a less common name. Ian Cairns 23:36, 19 Jul 2004 (UTC)

- Yup, seems logical enough. Edd 20:12, 20 Jul 2004 (UTC)

- Move completed. Thanks for your assistance. Ian Cairns 21:12, 20 Jul 2004 (UTC)

Why is the tauon actually called like that?
- It's not called the "tauon". It is called either the "tau" or the "tau lepton". As a reference I offer you Martin Perl's nobel prize citation, for example. On the Wikipedia page about Perl, someone had added a note "tauon" after the correct name "tau lepton". I had been wondering why this page was so strangely named since I first came to Wikipedia, and never bothered reading this talk page until now and discovering what had happened. Anyway I've removed every "tauon" I can find from Wikipedia. If necessary a note on the "tauon" name can be added here. --DannyWilde 15:15, 28 November 2005 (UTC)

- I think it's great that the tau's primary page is under "tau lepton", since that's by far the most common usage. But perhaps it's a bit overzealous to remove all references to "tauon". It's certainly not absent from the literature, and it does follow the standard "(foo) (lept/mes)on" --> "(foo)on" rule. I'm going to add a note on the subject at the top. -- Xerxes 16:09, 28 November 2005 (UTC)
- A note on this page is enough, other references should be removed. Funnily enough I used to think the name was "tauon", I can't remember where I got the impression from. --DannyWilde 02:02, 29 November 2005 (UTC)
- I had a good look on the Google but I couldn't find any clues about where "tauon" comes from. Interestingly I found lots of pages by astronomers using the word "tauon". I couldn't find any particle physicists using the word "tauon", although I found it being used on a couple of particle physics-related sites, for example in a speech by a non-physicist held on the SLAC site. Also, it appears in lots of these amateur guides to physics. Anyway, I have no idea where the "tauon" name comes from, but so far I see no evidence at all of its being used in particle physics. --DannyWilde 07:45, 29 November 2005 (UTC)

I think the Feynman diagram of the tau decay may be wrong. I believe at the initial decay, there should be the W- shown, and a tau-neutrino, rather than the anti-tau neutrino shown (as per conservation of lepton 'family' number, which should apply in this case). Can anyone confirm this?
- You are right. the arrow in the other neutrino is also pointing in the wrong direction. Does anybody know how to fix this kind of image file? Dauto 06:47, 12 May 2007 (UTC).
- There's something wrong with the Decay section; the decay branching probabilities don't add up to 100% and there's a reference to a commented-out image being incorrect in the article text. I've added the disputed-section template to the section until someone who understands what's going on can come and fix it. 75.15.155.179 (talk) 06:43, 7 April 2008 (UTC)
