Key terms in this lesson
- Weak nuclear force
- The fundamental interaction responsible for beta decay, in which particles interact through the exchange of W bosons.
- Pion
- A meson, made of a quark-antiquark pair, that may be positively charged, negatively charged or neutral; produced through the strong interaction and decaying through the weak interaction.
- Kaon
- A strange meson, produced through the strong interaction and decaying through the weak interaction, with a rest mass between that of a pion and a proton.
