    Beta Beta decay Decay
Click For Summary
SUMMARY

The discussion centers on the process of beta decay, specifically the role of the W- boson in the emission of an antineutrino and an electron. The W- boson, which has a spin of 1, decays into an antineutrino and an electron, both of which are spin-1/2 particles. This confirms that the emitted electron also possesses a spin of 1/2, aligning with the properties of fermions. The provided links to HyperPhysics serve as additional resources for understanding these concepts.

PREREQUISITES
  • Understanding of beta decay processes

Hello fellow physicists and mathematicians!

I am 15 years of age and trying to understand beta decay. At present I understand how the proton turns into a neutron etc... The problem is I do not understand how the decay of a W- boson turns into an antineutrino. I've read that the W- boson has spin of 1, ad the antineutrino a spin of 1/2. Does this mean the electron also emitted by decay of the w- boson has a spin of 1/2?
