sparticle

noun ˈspɑːtɪk(ə)lˈspɑrdək(ə)l
Physics
  • A hypothetical subatomic particle predicted by supersymmetry, which is the boson equivalent of a known fermion.

    every baryonic particle should have a supersymmetric twin: a sparticle
    Example sentencesExamples
    • The reason physicists haven't yet observed sparticles might be because they are so much heavier than their normal sister particles, so they decay far too quickly.
    • Top among all of these theories was always supersymmetry, the idea that every known elementary particle has one or more heavier partners, known as sparticles.
    • Should these "sparticles" exist, perhaps they might explain the existence of dark matter that we know pervades the entire Universe, but have little idea what it is.
    • "These are called sparticles - super particles - which make up, we think, dark matter, which in turn makes up 10 times more matter than ordinary matter."
