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)

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)

[edit] 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)

[edit] 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)

[edit] Further reading

  • The following analysis addresses how muons cooperate in the creation of the proton and it's integrated in the concepts of the Physics of Creation:

I added a little while ago this online publication about the muon by a British Physicist, with vast publication in these fields since the 60's. I am not acknowledge with any publication which disagrees with this author' statements/findings. However, it was removed by an user with the statement "remove crap biblical reference"!?. Please can you provide the readers whith your perspective of why, and where, does the author fails in the publication provided? Thank you in advance! --88.214.161.29 06:53, 6 August 2006 (UTC)

[edit] 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)

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. SBHarris 23:30, 12 October 2006 (UTC)

[edit] 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?

[edit] 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)

[edit] 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)

[edit] 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)
