释义

Definition of superpartner in English:

superpartner

nounˈsuːpəpɑːtnəˈsupərˌpɑrtnər
Physics
  • Each of the hypothetical particles which are supersymmetric counterparts of established particles in the standard model of particle physics.

    the theory of supersymmetry states that each fundamental particle has a superpartner
    Example sentencesExamples
    • Data on the quark and lepton masses and on their superpartner masses may provide major clues to teach us about string theory.
    • Then on integrating out the superpartners we will recover the standard model as a low energy effective theory with its quadratically divergent Higgs mass.
    • It's called the gravitino because it is the superpartner of the graviton.
    • The superpartner of a standard particle is called a sparticle.
    • When computing quantum corrections to the Higgs mass in supersymmetry one discovers an amazing result: each Standard Model particle and its superpartner give equally large contributions, but they are opposite in sign and so cancel each other out exactly!

Origin

1970s: from + super + partner.
