IB Physics SL E.3.9 Neutrinos & antineutrinos
Practise identifying the correct neutrino or antineutrino in beta decay, then completing weak-interaction equations and Feynman diagrams accurately.
How this is tested
- complete a beta-decay Feynman diagram with the correct neutrino line label and arrow direction
- use the decay equation to match beta-minus with an antineutrino and beta-plus with a neutrino
- account for missing beta-decay energy by stating in the equation that a neutrino carries part of it
