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.
24 gru 2014 · The weak force is one of the four fundamental forces that govern all matter in the universe (the other three are gravity, electromagnetism and the strong force). While the other forces...
The Weak Interaction. The weak interaction accounts for many decays in particle physics, e.g. μ. − → − e ̄νe νμ. − τ − → e ̄νe ντ π. + → − μ ̄νμ n → − pe ̄νe. Characterised by long lifetimes and small interaction cross-sections.
There are four fundamental forces at work in the universe: the strong force, the weak force, the electromagnetic force, and the gravitational force. They work over different ranges and have different strengths. Gravity is the weakest but it has an infinite range.
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.
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 Force. One of the four fundamental forces, the weak interaction involves the exchange of the intermediate vector bosons, the W and the Z. Since the mass of these particles is on the order of 80 GeV, the uncertainty principle dictates a range of about 10-18 meters which is about 0.1% of the diameter of a proton.
