gauginon.
/ɡeɪˈdʒiːnəʊ/, U.S. /ɡeɪˈdʒinoʊ/ Particle Physics.
A hypothetical particle which is the supersymmetric fermion counterpart of a gauge boson, with a spin of ½ instead of 1.Examples of gauginos are gluinos, gravitinos, winos, and zinos.

1982 A. Salam in Philos. Trans. (Royal Soc.) A. 304 144 One may deduce..the Lagrangian for a Higgs (spin-zero) field from a Lagrangian for spin-½ quarks. Likewise, gauge bosons (spin 1) and gravitons (spin 2) would be accompanied by and interact with gauge fermions (gauginos) and spin-3/ 2 gravitons, respectively, in a supersymmetric theory.
1989 P. D. B. Collins et al. Particle Physics & Cosmol. x. 243 Gauge bosons are partnered by spin-½ gauginos, and these cannot be identified with any of the quarks and leptons. So the latter have to be partnered by new spin-0 squarks and sleptons.
2001 Physics Lett. B. 500 22 Searches for pair production of gauginos and squarks in e+ e− collisions at a centre-of-mass energy of 189 GeV have been performed.
2005 L. Randall Warped Passages xvii. 347 Another interesting idea was called gaugino mediation. The idea was to communicate supersymmetry breaking not through the graviton, but instead through gauginos, the supersymmetric partners of the gauge bosons.
