Reference: AQA
The interaction responsible for muon decay, in which a negative muon transforms into an electron plus a muon neutrino and an electron antineutrino.
The interaction through which strange particles decay, which does not conserve strangeness and is much slower.
The change of quark character in beta decay is a weak interaction, not a strong or electromagnetic one.
