Pic including the W- exchange depiction edit

 
Feynman diagram of a negative beta decay, including the "correct" depiction of W- exchange, right?

Correct me if I'm wrong, but isn't the depiction og the W- exchange wrong? It is depicted as a Photon-exhange, with a wavy line. Weak force interactions are supposed to be written with dashes, right? Add my attempted improvement if you agree, or tell me if I'm wrong.. ;) Thγmφ (talk) 19:26, 4 April 2009 (UTC)Reply

Direction of antineutrino edit

Direction of antineutrino should be changed or it should be changed to neutrino.--MathFacts (talk) 20:46, 15 September 2009 (UTC)Reply

Right. Needs to be fixed. —Preceding unsigned comment added by 130.212.16.149 (talk) 00:32, 17 June 2010 (UTC)Reply

Direction of electron antineutrino edit

An antiparticle travelling forwards in time is the same as its particle counterpart travelling backwards in time, therefore the diagram is incorrect?

The W- boson decays into an electron antineutrino and an electron, not an electron neutrino (which is what this diagram, due to the direction of travel in time, depicts). Am I wrong? —Preceding unsigned comment added by Makkasu (talkcontribs) 14:11, 11 October 2009 (UTC)Reply

Either flip the direction of the antineutrino or change it to a neutrino. The diagram currently depicts an electron antineutrino going back in time—that's just an ordinary electron neutrino going forward in time, which is not the correct decay product. — Preceding unsigned comment added by 128.120.121.43 (talk) 20:28, 22 March 2012 (UTC)Reply
