A hypothetical particle which is the supersymmetric fermion counterpart of a Higgs boson, with spin ½ instead of 0.
1983R. Barbieri & L. Maiani in Nucl. Physics (B.) 22433 We shall consider effects associated with the types of new particles:..(ii) fermionic superpartners of the SU(2)L{earth}U(1) vector bosons and of the Higgs bosons (gauginos and higgsinos). 1988Astrophysical Jrnl. 32516 Assuming that generic higgsinos or Majorana neutrinos (both neutral fermions) of mass approximately 15–20 GeV make up the dark matter in the galactic halo, we show that their annihilation products can account for the entire spectrum of observed cosmic-ray antiprotons. 1996Sci. 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. |
