Would anyone object if I rewrote this page from a particle physics point of view? The main article on the Cauchy distribution already covers the mathematical properties of the function. I'll wait a while before messing around with it to see if there are any comments. Thanks. HEL 02:27, 14 October 2006 (UTC)
I took a shot at rewriting the page. If anyone objects to the changes, please let me know! HEL 00:37, 20 October 2006 (UTC)
Could someone give a reference for a textbook or a paper which covers the theoretical background, especially the mentioned connection to propagators? —Preceding unsigned comment added by 22.214.171.124 (talk) 18:06, 25 March 2010 (UTC)

The provided formula is, of course, incorrect. It is not E^2 - M^2 in the denominator (subtraction of two quantities out of which one is Lorentz-invariant and the other is not is a rare thing). It is P^2 - M^2, where P is the 4-momentum. — Preceding unsigned comment added by 126.96.36.199 (talk) 21:01, 26 June 2011 (UTC)
Skip the aggressively clueless "of course", please. It is reiterated, twice, that the relativistically invariant variable involved is evaluated at the center of mass of the decaying particle to E2. Cuzkatzimhut (talk) 19:27, 15 May 2014 (UTC)
