Photino
From Wikipedia, the free encyclopedia
A photino is a hypothetical subatomic particle, the fermion WIMP superpartner of the photon predicted by supersymmetry.[1] It is an example of a gaugino. Even though no photino has ever been observed so far, it is expected to be the lightest stable particle in the universe.[2]
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. It mixes with the superpartners of the Z boson (zino) and the neutral higgs (higgsino) to the neutralino.
