fundamental particle

Noun
  1. (physics) a particle that is less complex than an atom;
    Regarded as constituents of all matter (synset 109294991)
    referred to in: natural philosophy, physics - the science of matter and energy and their interactions
    is a type of: particle, subatomic particle - a body having finite mass and internal structure but negligible dimensions
    subtypes:
    • antilepton - the antiparticle of a lepton
    • antiparticle - a particle that has the same mass as another particle but has opposite values for its other properties; interaction of a particle and its antiparticle results in annihilation and the production of radiant energy
    • antiquark - the antiparticle of a quark
    • hadron - any elementary particle that interacts strongly with other particles
    • lepton - an elementary particle that participates in weak interactions; has a baryon number of 0
    • quark - (physics) hypothetical truly fundamental particle in mesons and baryons; there are supposed to be six flavors of quarks (and their antiquarks), which come in pairs; each has an electric charge of +2/3 or -1/3
    • strange particle - an elementary particle with non-zero strangeness
    • cosmic string, string - (cosmology) a hypothetical one-dimensional subatomic particle having a concentration of energy and the dynamic properties of a flexible loop
    • weakly interacting massive particle, wimp - a hypothetical subatomic particle of large mass that interacts weakly with ordinary matter through gravitation; postulated as a constituent of the dark matter of the universe
    is a part of: atom - (physics and chemistry) the smallest component of an element having the chemical properties of the element
    same as: elementary particle
