weak interaction, force

n

(Physics / General Physics) Physics an interaction between elementary particles that is responsible for certain decay processes, operates at distances less than about 10^-15 metres, and is 10¹² times weaker than the strong interaction. The weak interaction and electromagnetic interactions are now described by the unifying electroweak theory Also called weak nuclear interaction, force See interaction [2] electroweak interaction
