The weak interaction is one of the four fundamental forces of nature, responsible for mediating processes that change the flavor of quarks and leptons, such as beta decay. Unlike the strong interaction, which binds quarks together, the weak force is necessary for certain particle decays that allow matter constituents to transform into different forms of matter. This force is mediated by carrier particles, specifically the W and Z bosons, and is crucial for understanding radioactive decay and the processes governing the behavior of particles within atomic nuclei. Its range is extremely short, making it manifest primarily within the subatomic domain.
