← Back to Matter by scale

A gauge field is a type of field that mediates interactions between particles. In quantum theory, these interactions arise from underlying symmetry principles.

Gauge fields mediate interactions between particles through exchange processes.

Description

Gauge fields emerge from the requirement that physical laws remain invariant under certain transformations (symmetries). These fields are responsible for fundamental interactions such as electromagnetic, weak, and strong interactions.

In quantum field theory, interactions between particles can be described as exchanges of quanta of gauge fields, often represented as bosons.
