charge is a Book II topic in the Quantum Collection. Charge is a fundamental property of a particle that determines how it participates in interactions. The most familiar example is electric charge, which governs electromagnetic behavior. Charge is conserved in known physical processes and acts as a label for how a particle couples to gauge fields. Electric charge controls electromagnetic interactions, while color charge and weak charges appear in the strong and weak interactions. In quantum theory charge is tied to symmetry, selection rules, current operators, and the classification of particles.
Description
Particles can carry different types of charge depending on the interaction considered. For example, electric charge determines electromagnetic interactions, while other forms of charge determine participation in other fundamental forces.
Charge is conserved in physical processes and plays a central role in determining how particles influence each other.
Properties
- determines interaction strength
- conserved quantity
