1. Also called: weak nuclear interaction.   weak nuclear force.  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.

Origin of weak interaction

Example Sentences

While the electromagnetic force and gravity are quotidian to human interactions and everyday life, and the strong force is what binds atomic nuclei together, the weak interaction is not as overtly visible.

The prizewinners studied weak-force interactions at high energies by creating a beam of neutrinos, which do not interact through the strong force but do so by the weak interaction.

From Washington Post

From Scientific American

To be clear, we are certainly not the first to connect homochirality with the weak interaction.
