supersymmetryn.
/suːpəˈsɪmᵻtri/, /sjuːpəˈsɪmᵻtri/, U.S. /ˌsupərˈsɪmətri/ Symmetry of a more general type or of a higher order; (Physics) a very general type of mathematical symmetry proposed as relating fermions and bosons.One of the implications of supersymmetry in Physics is that many known subatomic particles should have corresponding superpartners with a spin differing by ½. The use of the word in this context originated with Salam and Strathdee (quot. 1974).

1941 Amer. Jrnl. Psychiatry 98 125/1 Symmetry is a constructive factor in any good design. But in schizophrenia this principle..stands out in contrast to the meagerness or even emptiness of the design as a whole. It is a formalistic, external symmetry. One can speak of this as ‘super-symmetry’.
1958 Progr. Theoret. Physics 19 639 If there is the super symmetry between Λ and Σ when gK2/ℏc = e2/ℏc = 0, Λ and Σ must have the same intrinsic parity.
1961 S. L. Glashow & M. Gell-Mann in Ann. Physics 15 297 One of them might play a role in the physics of the strong interactions if there is an underlying super-symmetry, transcending charge independence, that is badly broken.
1966 Progr. Theoret. Biol. 13 364 Higher molecular complexity in chromosomes may be produced by..compounding several primary information molecules..into a single super-complex, leading to super-symmetry.
1966 Ann. Physics 38 554 The spectrum happens to coincide with that contained in the (6*, 6)–(6, 6*) representation of the recently proposed U6 × U6 supersymmetry.
1974 A. Salam & J. Strathdee in Physics Lett. B. 51 353/1 These authors [sc. J. Weiss and B. Zumino, 1974]..designate this Fermi-Bose symmetry by the expression ‘super-gauge’. Since the word ‘gauge’ has come to be more commonly associated with ‘gauges of the second kind’ or local symmetries, it is confusing to use super-gauge to describe what is indeed a global symmetry of fermions and bosons. We suggest therefore that the expression ‘super-symmetry’ might be more appropriate.
1975 S. Ferrara & B. Zumino in Nucl. Physics B. 87 207 Supersymmetry transformations form an extended Lie algebra.
1977 Physics Today Apr. 49/3 As far as I know, the only natural way to keep a scalar boson massless is to have a ‘supersymmetry’,..which puts scalar fields in the same multiplet as massless fermion fields.
2001 N.Y. Mag. 14 May 93/1 Paintings whose images draw on the ‘supersymmetry’ physics theory that every particle of matter possesses a ‘shadow’ particle.
2005 L. Randall Warped Passages xvii. 347 The idea was to communicate supersymmetry breaking not through the graviton, but instead through gauginos, the supersymmetric partners of the gauge bosons.
