Axino

The axino is a hypothetical elementary particle that is predicted by some theories of particle physics . The Peccei-Quinn theory tries to explain the observed phenomenon , known as the strong CP problem , by introducing a hypothetical real scalar particle called the axion . If one introduces supersymmetry into the model, a fermionic super partner for the axion, the axino , and a bosonic super partner, the saxion , are predicted. They are all bundled by a chiral superfield .

The axino would then be the lightest supersymmetric particle in such a model. Partly because of this property, it is considered a candidate for the composition of dark matter .
