1982 Physics Lett. B. 116 287/2 The lightest supersymmetric particle is a neutral Higgsino with a mass of a few GeV, which is essentially stable.
1996 Sci. Amer. July 15/2 The selectron would then decay into a photon and a photino, and the photino into a photon and a Higgsino, the superpartner of the hypothetical Higgs boson.
2004 B. Greene Fabric of Cosmos (2005) v. xiv. 433 Another promising proposal involves supersymmetric particles, especially the photino, the zino, and the higgsino.
2011 National Post (Canada) (Nexis) 3 Dec. a12 There might turn out to be a whole family of new particles, ‘Higgsinos’ perhaps, or a new class of subatomic quark, each of which contributes something unique to the ‘mass-ification’ of the universe.
