Pic including the W- exchange depiction

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)

Direction of antineutrino

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

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

Direction of electron antineutrino

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 (talk • contribs) 14:11, 11 October 2009 (UTC)

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)
