  2. Elementary particle - Wikipedia

    en.wikipedia.org/wiki/Elementary_particle

    The Standard Model of particle physics contains 12 flavors of elementary fermions, plus their corresponding antiparticles, as well as elementary bosons that mediate the forces and the Higgs boson, which was reported on July 4, 2012, as having been likely detected by the two main experiments at the Large Hadron Collider (ATLAS and CMS).

  3. 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.

  4. 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.

  5. List of particles - Wikipedia

    Since then, the particle has been shown to behave, interact, and decay in many of the ways predicted for Higgs particles by the Standard Model, as well as having even parity and zero spin, two fundamental attributes of a Higgs boson. This also means it is the first elementary scalar particle discovered in nature.

  6. Flavour (particle physics) - Wikipedia

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

    In atomic physics the principal quantum number of an electron specifies the electron shell in which it resides, which determines the energy level of the whole atom. Analogously, the five flavour quantum numbers ( isospin , strangeness , charm , bottomness or topness ) can characterize the quantum state of quarks, by the degree to which it ...

  7. Timeline of particle discoveries - Wikipedia

    en.wikipedia.org/wiki/Timeline_of_particle...

    Elementary particles from the Standard Model of particle physics that have so far been observed. The Standard Model is the most comprehensive existing model of particle behavior. All Standard Model particles including the Higgs boson have been verified, and all other observed particles are combinations of two or more Standard Model particles.

  8. Toroidal ring model - Wikipedia

    en.wikipedia.org/wiki/Toroidal_ring_model

    The toroidal ring model, known originally as the Parson magneton or magnetic electron, is a physical model of subatomic particles. It is also known as the plasmoid ring, vortex ring, or helicon ring. This physical model treated electrons and protons as elementary particles, and was first proposed by Alfred Lauck Parson in 1915.

  9. 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 ...
