The electroweak interaction is a unified description of two of the four fundamental forces of nature: electromagnetism and the weak nuclear force, which was successfully formulated in the 1960s and is a cornerstone of the Standard Model of particle physics. This unification explains how these forces manifest at high energy levels and involves the exchange of W and Z bosons, which mediate the weak force, and the photon, which mediates electromagnetic interactions.

Electroweak Interaction

fundamental forces of nature

Electromagnetism is a fundamental force in nature responsible for electric and magnetic phenomena, described by Maxwell's equations, which unify electricity, magnetism, and light as manifestations of the same force. It plays a crucial role in modern technology, from power generation and transmission to telecommunications and electronic devices.

The weak nuclear force is one of the four fundamental forces of nature, responsible for processes like beta decay in atomic nuclei. It is characterized by its short-range and the ability to change the flavor of quarks, playing a crucial role in the fusion reactions that power stars.

weak nuclear force

The Standard Model of Particle Physics is a well-established theory that describes three of the four known fundamental forces in the universe and classifies all known subatomic particles. It successfully explains electromagnetic, weak, and strong nuclear interactions but does not incorporate gravity or account for dark matter and dark energy.

Standard Model of particle physics

The unification of forces is a fundamental pursuit in physics aiming to describe all fundamental forces of nature within a single theoretical framework. This endeavor seeks to extend the success of the electroweak unification to include the strong nuclear force and gravity, potentially leading to a Grand Unified Theory or even a Theory of Everything.

Mediated interactions

A photon is a fundamental particle of light and electromagnetic radiation, which exhibits both wave-like and particle-like properties. It is massless, travels at the speed of light in a vacuum, and is the quantum of the electromagnetic field, playing a crucial role in quantum mechanics and electromagnetism.

photon

Electromagnetic interactions are fundamental forces that occur between charged particles, mediated by the exchange of virtual photons. These interactions govern a wide range of phenomena including the behavior of atoms, the propagation of light, and the forces in electrical and magnetic fields.
