[edit] Matrix elements

Is there a reason why the matrix is not symmetric? --HappyCamper 02:46, 18 August 2006 (UTC)

There is no reason that it should be. The only requirement is that it be unitary. -- Josh Thompson 01:31, 19 November 2006 (UTC)

[edit] Doesn't appear in search?

A wikipedia search on 'CKM' doesn't find this page. Is there a way to fix that? -- Josh Thompson 01:32, 19 November 2006 (UTC)

I made this edit. Will it suffice? --HappyCamper 02:55, 19 November 2006 (UTC)
Works for me. Thanks. -- Josh Thompson 22:30, 20 November 2006 (UTC)

[edit] A minor issue

I just have a little quibble with the description of the vector on the left side of equation below as being a vector of strong force eigenstates, since the vector on the right side also is a strong force eigenstate vector. More appropriate would be, it seems, to call it a vector of mass eigenstates.

\begin{bmatrix} V_{ud} & V_{us} & V_{ub} \\ V_{cd} & V_{cs} & V_{cb} \\ V_{td} & V_{ts} & V_{tb} \end{bmatrix} \begin{bmatrix} \left| d \right \rangle \\ \left| s \right \rangle \\ \left| b \right \rangle \end{bmatrix} = \begin{bmatrix} \left| d' \right \rangle \\ \left| s' \right \rangle \\ \left| b' \right \rangle \end{bmatrix} —The preceding unsigned comment was added by Dauto (talk • contribs) 19:38, 9 April 2007 (UTC).

[edit] strong force eigenstate

what's an eigenstate of the strong force? IMHO this is a misconception, and the article should read "mass eigenstate" instead. Please confirm. - Saibod 14:09, 20 September 2007 (UTC)

I don't know what, if anything I can add to this discussion, but here's a go at it. In his The Road to Reality (which is my only source on things in this area), Roger Penrose introduces a few of the concepts dealt with in this article (specifically the Cabibbo angle) through discussion of the K0 meson, which he describes as "an eigenstate of strong interactions" (his italics, not mine). If that applies here or not, I couldn't begin to say. 204.52.215.69 (talk) 15:40, 12 December 2007 (UTC)

[edit] Uncertainties

Why aren't uncertaities quoted in this article? Any particular reason besides "nobody's done it yet"? —Preceding unsigned comment added by Dauto (talk • contribs) 15:55, 5 February 2008 (UTC)
