Physics:Quantum particles/mass
mass is a Book II topic in the Quantum Collection. Mass is a fundamental property of a particle that determines its resistance to acceleration and its contribution to energy. It plays a central role in both classical and quantum physics. In quantum physics mass appears both as a parameter in wave equations and as a property linked to energy, inertia, and relativistic dispersion. Particle masses shape thresholds, decay rates, bound-state spectra, and the range of forces. In the Standard Model, elementary-particle masses are connected with electroweak symmetry breaking and interactions with the Higgs field.
Description
Mass measures how a particle responds to forces and how it contributes to the total energy of a system. In quantum theory, mass affects how particles propagate and interact.
Mass is closely related to energy and plays a role in determining the behavior of particles in fields and interactions.
