Axino



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.

Additional recommended knowledge

The axino has been predicted to be the lightest supersymmetric particle in such a model.[1] In part due to this property, it is considered a candidate for the composition of dark matter.[2]
