42 feynman diagram beta decay
Beta decay. The weak interaction is responsible for beta decay. The exchange particles for the weak interaction are the W+, the W- and the Z0. We can describe the process as follows. A neutron changes into a proton by emitting a W -, which quickly decays into an electron and an antineutrino. 1. Which Feynman diagram shows beta-plus (β) decay?
