The weak interaction is responsible for the radioactive decay of atoms. The exchange particle that carries this force is the W–, W+ or Z0 boson. The type of exchange particle depends on the type of interaction. β decay. β – and β + decay are examples of the weak interaction in action.
In nuclear physics and particle physics, the weak interaction, also called the weak force, is one of the four known fundamental interactions, with the others being electromagnetism, the strong interaction, and gravitation.
6 wrz 2024 · weak interaction, a fundamental force of nature that underlies some forms of radioactivity, governs the decay of unstable subatomic particles such as mesons, and initiates the nuclear fusion reaction that fuels the Sun.
The weak interaction, also known as the weak nuclear force, is one of the four fundamental forces of nature responsible for processes like beta decay in radioactive materials and interactions involving neutrinos.
The weak interaction is the only process in which a quark can change to another quark or a lepton to another lepton (flavor change). Neither the strong interaction nor electromagnetic permit flavor changing. This fact is crucial in many decays of nuclear particles.
30 wrz 2021 · The weak force is responsible for the fusion of neutrons and protons to form a deuteron. It is significant in nucleosynthesis and stellar interiors. The theory describing its behavior of weak interaction and effects is often called quantum flavourdynamics (QFD).
In QED/QCD interaction does not change “type” of particle if possible, only charge quantum number gets changed. In contrast: Weak interactions trigger β-decays (n → p or d → u) Must embed this in a “gauge structure”, putting different particle species in one multiplet, with charges.
