The axino is a hypothetical elementary particle predicted by some theories of particle physics . Peccei–Quinn theory attempts to explain the observed phenomenon known as the strong CP problem by introducing a hypothetical real scalar particle called the axion . Adding supersymmetry to the model predicts the existence of a fermionic superpartner for the axion, the axino, and a bosonic superpartner, the saxion . They are all bundled up in a chiral superfield .
The axino has been predicted to be the lightest supersymmetric particle in such a model.[1] dark matter .[2]
The supermultiplet containing an axion and axino has been suggested as the origin of supersymmetry breaking, where the supermultiplet gains an F-term expectation value. [3]
