A photino is a hypothetical subatomic particle, the fermion WIMP superpartner of the photon predicted by supersymmetry.[1][2] 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.[3] It is proposed that photinos are produced by sources of [[ultra-high-energy cosmic rays].[4] Xiang He, an independent researcher, states in his ebook entitled A Rotating Universe that the neutrino is in fact the photino. This logical conclusion is based on Sternglass’ discovery that the chargeless neutrino is a special form of radiation just like the photon but with only half of the latter’s spin. This idea was considered by de Broglie before (see Sternglass, Before the Big Bang, 2nd edition, p. 115).

Photino numbers

[edit]

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.[5] It mixes with the superpartners of the Z boson (zino) and the neutral higgs (higgsino) to form the neutralino.
