Muons have a mass that is 207 greater than the electron

Units, please. 207 what? -- Merphant

Ration bewteen quantities doesn't depend on the units and the units are given: (105.6 MeV) -- looxix 23:31 Apr 19, 2003 (UTC)

Ok, sorry, I see. -- Merphant

Is it legal to use a textbook as the source for a Wikipedia article? - ElusiveByte 20:53, Sep 21, 2003 (UTC)

Yes. Strait 16:37, 13 July 2006 (UTC)[reply]

The muon is also known as a mu meson

Historically correct, but nowadays the term meson is reserved for quark/antiquark particles. The term mu meson is now a misnomer.

muon ... is a collective name

Is that really true? IMHO muon refers only to μ^-, while μ⁺ is called an antimuon.

Herbee 2004-02-07

Generally, physicists will refer to either as a "muon." Sometimes we'll even say "positive muon" and "negative muon" for clarity. -- SCZenz 17:07, 28 August 2005 (UTC)[reply]

Wobble

http://www.aip.org/pnu/2002/split/600-1.html

Can someone who understands this fill us in on the wobble ? Wizzy…☎ 14:52, August 28, 2005 (UTC)

I just added two external links to the main page, and I was hoping that someone that understands it better than I do would write about it or know of a link in wiipedia to more information. Bubba73 15:58, August 28, 2005 (UTC)

I understand it, but I may need to find (or draw) a picture to explain it more clearly than those pages do. I'll put it on my list. -- SCZenz 17:07, 28 August 2005 (UTC)[reply]

CERN dimuon experiments

Took out the bit about CERN doing neutrino+proton-->dimuon work. Does anybody know the actual name of this experiment, if it existed? Similar work was done at Fermilab and SLAC, but I didn't turn up anything at CERN. -- Xerxes 22:30, 5 November 2005 (UTC)[reply]

Lifespan?

Quoting from the article:

"The muons from high energy cosmic rays are often moving at very high velocities, so despite their short lifetime, the time dilation effect of special relativity...."

What exactly is the typical lifespan of a muon? Aside from the above-mentioned allusion to a "short lifetime", the article says nothing about that. 24.6.66.193 20:50, 12 October 2006 (UTC)[reply]

It's the second line of the article. Half-life 2.2 microseconds. About 660 m = .66 km at the speed of light. Which would make it tough for many muons to get down from the upper atmosphere, were it not for relativistic time-dilation. S B H arris 23:30, 12 October 2006 (UTC)[reply]

Dirac and the muon

Somewhere in the depths of my memory, I recall that Paul Dirac, in an interview, said that he was working on a theory which would make the muon "something like" an excited state of the electron. Does anyone know any further details?

redirect

Does anyone know why AntiMuon redirects here?

Where else would it redirect? Or what would it say as a separate article? -- SCZenz 02:13, 30 October 2006 (UTC)[reply]

It would say the same thing as this article, but time-reversed.216.80.110.88 (talk) 01:16, 30 January 2009 (UTC)[reply]

Ratings

I noticed that this article didn't have an Assessment or Importance rating. I rated importance as "Top" (subject is a "must-have" for a print encyclopedia). I put the Assessment as B, but I would appreciate if others have a more well-formed opinion (I am new at this). By the way, I love the fabulous picture of the moon's shadow in muons.

This paragraph has not much (semantic) sense, specially the last two lines. —Preceding unsigned comment added by 128.227.179.188 (talk) 19:22, 6 December 2007 (UTC)[reply]

Energy paragraph unclear

"Since the production of muons requires an available COM frame energy of over 105 MeV, neither ordinary radioactive decay events nor nuclear fission and fusion events (such as those occurring in nuclear reactors and nuclear weapons) are energetic enough to produce muons. Only nuclear fission produces single-nuclear-event energies in this range, but due to conservation constraints, muons are not produced."

This paragraph is confusing. First, it says that muons are not produced in nuclear fission, then the next sentence says they are. Which one is accurate? Duckyphysics (talk) 02:47, 28 March 2008 (UTC)[reply]

Copy-editing

Uhh, this page requires some serious copy-editing. There is some duplicated stuff and a lot of random external links directly in the article. They should be screened for redundancy, importance and availability (the only one given as ref-tag seems to be dead). --Pjacobi (talk) 00:26, 13 June 2008 (UTC)[reply]

Font

Am I the only one that finds the font used for the elementary particles in text mode to be terrible? The simbol for the muonic neutrino might as well be $v_{u}$ instead of $\nu _{\mu }\,$ and I wouldn't be able to tell the difference. there's got to be a better way to do it. I would change it myself if I knew how to do it. Dauto (talk) 04:45, 18 January 2009 (UTC)[reply]

There's an ongoing discussion about that somewhere I think. I'll try to find a link, else I'll start one on Template talk:SubatomicParticle. Headbomb {^ταλκ_{κοντριβς} – WP Physics} 05:54, 18 January 2009 (UTC)[reply]

Muon Decay Diagram

Isn't the arrow depicting every anti-particle supposed to be facing the opposite direction of normal time? Please tell me if I've misunderstood something.. Thγmφ (talk) 19:42, 6 April 2009 (UTC)[reply]
