单词	superpartner
释义	superpartner /ˈsuːpəpɑːtnə / noun 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... Data on the quark and lepton masses and on their superpartner masses may provide major clues to teach us about string theory. 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! It's called the gravitino because it is the superpartner of the graviton. Origin 1970s: from + super + partner.
