Particle physics, also known as high-energy physics, is the study of the fundamental constituents of matter and radiation, and the interactions between them. It aims to answer the question: "What is everything made of, and how does it stay together?" The crowning achievement of this field is the Standard Model, a mathematical framework that successfully describes three of the four fundamental forces of nature (electromagnetism, the weak force, and the strong force). Through massive particle accelerators like the Large Hadron Collider (LHC), physicists recreate the conditions of the early universe to discover new particles and test the limits of our physical laws.

* '''Quark''' — Fundamental constituent of matter that combines to form hadrons (like protons and neutrons).
* '''Lepton''' — Fundamental particles that do not undergo strong interactions (e.g., electrons, neutrinos).
* '''Boson''' — Force-carrying particles (e.g., photon, gluon, W and Z bosons).
* '''Fermion''' — Matter particles; include quarks and leptons (obey Pauli exclusion).
* '''Gluon''' — The boson that carries the strong force, binding quarks together.
* '''Higgs Boson''' — The particle associated with the Higgs field, which gives mass to other elementary particles.
* '''Standard Model''' — The current theoretical framework of particle physics.
* '''Neutrino''' — An extremely light, neutral lepton that rarely interacts with matter.
* '''Hadron''' — A composite particle made of quarks (e.g., protons, neutrons, mesons).
* '''Antimatter''' — Matter composed of antiparticles, which have the same mass but opposite charge as regular particles.
* '''Strong Force''' — The interaction that binds quarks into hadrons and holds the atomic nucleus together.
* '''Weak Force''' — The interaction responsible for radioactive decay and nuclear fusion in stars.
* '''Color Charge''' — The property of quarks and gluons that mediates the strong interaction (analogue to electric charge).
