Weak Decay

Weak decay is a fundamental process by which certain particles transform into other particles through the weak nuclear force, one of the four fundamental forces in nature. This process often involves changes in the type or identity of particles, such as a neutron decaying into a proton, an electron, and an antineutrino. Unlike other interactions, the weak force can change the flavor of quarks inside particles, enabling these transformations. Weak decay is responsible for phenomena like radioactive decay and plays a crucial role in processes happening inside stars and the early universe.
