## Parent topics

## Subtopics

- Hadron [r]: A composite particle made up of quarks bound together by the strong force, such as a meson, proton, or a neutron.
^{[e]} - Lepton [r]: A spin 1/2 elementary particle, such as an electron, muon or neutrino, that is not subject to the strong force.
^{[e]} - Nuclear force [r]: The force holding assemblies of protons and neutrons together
^{[e]} - Quantum chromodynamics [r]: A quantum field theory which supposes that fundamental particles such as protons and neutrons are made up of interacting quarks and gluons.
^{[e]} - Quantum electrodynamics [r]: A relativistic theory of the interaction between electrically charged bodies based upon the exchange of photons, the quanta of the electromagnetic field.
^{[e]} - Weak force [r]: One of the four fundamental forces.
^{[e]}

- Higgs boson [r]: A massive spin-0 elementary particle, first proposed by Peter Higgs, that plays a key role in explaining the mass of other elementary particles.
^{[e]} - Maxwell equations [r]: Mathematical equations describing the interrelationship between electric and magnetic fields; dependence of the fields on electric charge- and current- densities.
^{[e]} - Electric charge [r]: A positive or negative property of matter that occurs as integral multiples of an elementary charge unit, and causes mutual repulsion of like-charged particles and mutual attraction of oppositely charged particles.
^{[e]} - Boson [r]: elementary particle with integral spin; composite system consisting of an even number of fermions.
^{[e]} - Hadron [r]: A composite particle made up of quarks bound together by the strong force, such as a meson, proton, or a neutron.
^{[e]} - Lepton [r]: A spin 1/2 elementary particle, such as an electron, muon or neutrino, that is not subject to the strong force.
^{[e]} - Photon [r]: elementary particle with zero rest mass and unit spin associated with the electromagnetic field.
^{[e]} - Meson [r]:
*Add brief definition or description* - Neutrino [r]: A stable fundamental subatomic particle of matter (no internal structure) classified as a lepton; for electron-associated neutrinos evidence pointing to a finite mass less than an electron, lacking electrical charge, extremely non-interacting with matter; evident in three flavors (varieties or types): electron neutrinos, muon neutrinos, and tau neutrinos, each with a charged partner, the electron, the muon, and the tau, respectively.
^{[e]} - Special relativity [r]: Theory of the effects of motion on observations of things such as length, time, mass and energy. The theory is based on the postulates that all laws of physics are the same in all inertial reference systems, and that the vacuum speed of light is a universal constant, independent of the speed of the source.
