noun

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, weak nuclear force interaction (sense 2), electroweak interaction

Weak Interaction

the short-range interaction between leptons responsible for beta decay and the decay of many long-lived elementary particles

n.

1. One of the four fundamental interactions of nature, mediated by the intermediate vector bosons and acting on leptons and quarks. It is responsible for the decay of many hadrons, for the beta decay of nuclei, and for the interactions of neutrinos. The weak interaction is weaker than the strong and electromagnetic interactions, but stronger than the gravitational interaction.

2. An instance of this interaction.
