Photino

A photino is a hypothetical subatomic particle, the fermion WIMP superpartner of the photon predicted by supersymmetry.<ref>Template:Cite journal</ref><ref>Template:Cite journal</ref> It is an example of a gaugino. Even though no photino has ever been observed so far, it is one of the candidates for the lightest supersymmetric particle in the universe.<ref>Template:Cite journal</ref> It is proposed that photinos are produced by sources of ultra-high-energy cosmic rays.<ref>Template:Cite journal</ref>

However, according to Sternglass’ relativistic electron-positron model, the photino has been observed but misnamed as the neutrino — a special form of radiation with half of the photon’s spin. This conclusion is consistent with de Broglie’s insight on the nature of the neutrino.

Photino numbers

Photinos have a lepton number 0, baryon number 0, and spin 1/2. With an R-parity of −1 it is a possible candidate for dark matter.<ref>Template:Cite book</ref> It mixes with the superpartners of the Z boson (zino) and the neutral higgs (higgsino) to form the neutralino.
