Hey your virtual photon need to be slanted because it cannot travel instantaneously (cant be faster than speed of light). Your virtual photon is horizontal implying it is faster that the speed of light.

For AQA a levle physics, would you get a mark for saying that the role of the exchange particles is to transfer momentum or would it be better to write transfer force? Thanks

At the end, is a neutrino or antineutrino produced? I thought it was an antineutrino to conserve lepton number? Great video by the way
