  2. Elementary particle - Wikipedia

    en.wikipedia.org/wiki/Elementary_particle

    Among the 61 elementary particles embraced by the Standard Model number: electrons and other leptons, quarks, and the fundamental bosons. Subatomic particles such as protons or neutrons , which contain two or more elementary particles, are known as composite particles .

  3. List of particles - Wikipedia

    This also means it is the first elementary scalar particle discovered in nature. Elementary bosons responsible for the four fundamental forces of nature are called force particles ( gauge bosons ). The strong interaction is mediated by the gluon , the weak interaction is mediated by the W and Z bosons, electromagnetism by the photon, and ...

  4. Quantum number - Wikipedia

    en.wikipedia.org/wiki/Quantum_number

    However, it should be understood that the elementary particles are quantum states of the standard model of particle physics, and hence the quantum numbers of these particles bear the same relation to the Hamiltonian of this model as the quantum numbers of the Bohr atom does to its Hamiltonian. In other words, each quantum number denotes a ...

  5. Standard Model - Wikipedia

    en.wikipedia.org/wiki/Standard_Model

    The Standard Model of particle physics is the theory describing three of the four known fundamental forces (electromagnetic, weak and strong interactions – excluding gravity) in the universe and classifying all known elementary particles.

    Standard Model of Particle Physics. The diagram shows the elementary particles of the Standard Model (the Higgs boson, the three generations of quarks and leptons, and the gauge bosons), including their names, masses, spins, charges, chiralities, and interactions with the strong, weak and electromagnetic forces.

  7. Flavour (particle physics) - Wikipedia

    en.wikipedia.org/wiki/Flavour_(particle_physics)

    In particle physics, flavour or flavor refers to the species of an elementary particle.The Standard Model counts six flavours of quarks and six flavours of leptons.They are conventionally parameterized with flavour quantum numbers that are assigned to all subatomic particles.

  8. Particle physics - Wikipedia

    en.wikipedia.org/wiki/Particle_physics

    Particle physics or high-energy physics is the study of fundamental particles and forces that constitute matter and radiation. The field also studies combinations of elementary particles up to the scale of protons and neutrons, while the study of combination of protons and neutrons is called nuclear physics.
