interaction is a Book II topic in the Quantum Collection. An interaction is a process by which particles influence one another through fundamental forces. In quantum theory, interactions are described as exchanges mediated by bosons. In quantum theory an interaction is not merely a classical push or pull. It is represented by couplings between fields, transition amplitudes, exchange particles, and conservation laws that determine which processes can occur. Interactions shape scattering, bound states, decay, radiation, and the structure of matter. They also provide the link between microscopic quantum rules and experimentally observed forces.
Description
Interactions determine how particles behave and combine. In modern physics, they are understood in terms of quantum fields, where particles interact through the exchange of quanta of these fields.
The known fundamental interactions include electromagnetic, weak, strong, and gravitational interactions.
