Category

edit

since the Klein-Gordon eqn is also in that category, I changed cat:equations to cat:PDE. If all field equations were classified there, they could even make up a subcategory of their own... — MFH:Talk 21:40, 30 March 2006 (UTC)Reply


The Gamma matrices convention

edit

In Weinberg's textbook, the gamma matrices are defined such that   and the metric  . This might need to be pointed out to avoid confusions.

Wrong mass term in the Lagrangian

edit

The mass term in the Lagrangian will be wrong without the antisymmetric product of two gamma matrices. —Preceding unsigned comment added by 128.122.53.167 (talk) 04:20, 23 February 2008 (UTC)Reply

Thank you for the comment. Can you provide some reference to the correct Lagrangian? -- þħɥʂıɕıʄʈʝɘɖı 18:01, 23 February 2008 (UTC)Reply

Maybe I'm being dense here, but does the   term in the Lagrangian suppose to signify  ? —Preceding unsigned comment added by 67.193.118.186 (talk) 14:45, 27 June 2010 (UTC)Reply


I have updated both the RS equation and the Lagrangian to the correct form; c.f. the already-referenced G. Velo, D. Zwanziger, Phys. Rev. 186, 1337 (1969). Yes, there is an antisymmetric gamma product in the mass term. Yes,  ; I have switched this to the more commonly used  . N.B. in the Velo and Zwanziger reference the lack of   in the definitions of   and  .

I intend to make citations on this page in-line, but I don't have more time at this very moment.

The "in need of attention from an expert" box was added by a bot; what more, if anything, do we want in this page so that we can remove said box?

I think S. Weinberg's books should give the correct formulaes. --B wik (talk) 18:57, 15 July 2011 (UTC)Reply

sigma notation

edit

Does the   notation in this article correspond to the   in the previous post? If so, can someone clarify this in the article itself? 109.153.12.132 (talk) 23:09, 26 May 2011 (UTC)Reply
