The simplest version of supersymmetry, which should be manifest at the GUT scale (~1016 GeV) and below, has as its key prediction that for every kind of particle that we have there should be an as-yet-undiscovered "supersymmetric partner particle" with the same quantum numbers and interactions except that the spin of this hypothetical partner particle differs from that of the known particle by half a unit. For example, the partner of the photon (spin 1) is the "photino" (spin ½), and the partner of the electron (spin ½) is the "selectron" (spin 0).

CONT

Le photino est électriquement neutre et son interaction avec la matière doit être infime. Donc, si cette particule est stable, elle peut très bien être quasiment invisible.
