Quick Summary

A photino is a hypothetical elementary particle required by theories of supersymmetry. It is associated with the photon, is thought to have mass, and interacts very weakly with ordinary matter. Photinos are postulated to be a constituent of the universe's dark matter. Supersymmetry, a concept in particle physics, proposes a symmetry between fermions and bosons. In this framework, known bosons like the photon are theorized to have fermionic partners, and the photino is the proposed supersymmetric partner to the photon.12
