← Back to Particles Book II

particle is a Book II topic in the Quantum Collection. A particle is a fundamental entity in physics that carries energy, momentum, and other physical properties. In quantum theory, particles are described as excitations of underlying fields. The quantum idea of a particle is subtler than a tiny classical object. A particle can be a localized excitation of a field, a member of an indistinguishable many-particle state, or a quasiparticle emerging inside matter. Its properties are represented by quantum numbers such as mass, spin, charge, flavor, and statistics. Particles are detected through interactions, not by following classical trajectories.

Description

Particles can be elementary, such as quarks and leptons, or composite, such as protons and neutrons. Their behavior is governed by quantum mechanics and quantum field theory.
