  1. 1982–
    A hypothetical subatomic particle which is the supersymmetric counterpart of the Z boson, having a spin of ½ instead of 1.

      The ‘zino’ (fermionic partner of the Z° gauge boson) combines with one combination of neutral fermionic Higgs.

      The Higgs can, for example, emit and reabsorb either a Z boson or its fermion superpartner, a Zino.

      Another promising proposal involves supersymmetric particles, especially the photino, the zino, and the higgsino.
