- physics an interaction between elementary particles that is responsible for certain decay processes, operates at distances less than about 10 –15 metres, and is 10 12 times weaker than the strong interaction. The weak interaction and electromagnetic interactions are now described by the unifying electroweak theoryAlso called: weak nuclear interaction, weak nuclear force See interaction (def. 2), electroweak interaction
- See weak force.
