And squarks, sleptons, ... gluinos and higgsinos. Actually, the
supersymmetric dual of the neutrino is the sneutrino. The neutralino is
a combination of, I think, the Zino, the photino and maybe a Higgsino
that ends up being the lightest supersymmetric particle. In a number of
theories, this particle cannot decay and turns out the be a great
candidate for dark matter.
