- n. The superpartner of the photon.
Sorry, no etymologies found.
No, wait, Baxter did that with his "photino birds".
It's one of the particles that are being mixed with others (photino, zino) to obtain the neutralinos.
So, for example, the supersymmetric partner of the photon, the photino, this would spin at half the rate of the photon.
So, the selectron, for example, would have an electric charge, and it would couple to the photino in the same way that the electron couples to the photon - and that's the way that electromagnetic radiation works, and TV and computers and so on.
A: Supersymmetry is an idea according to which in parallel to the particles that were made of, the electron for example, that goes around an atom, or the photon, which causes light, in parallel to those particles there would be other particles, call it the selectron, call it the photino, which have identical interactions.
