Description
In supersymmetric models, the lightest neutralino explains the whole dark matter abundance and predicts observable signals in direct and indirect searches. However, recent experiments constrain the natural parameter space for neutralino dark matter. On the other hand, if the neutralino is thermally underabundant, the axion is a good candidate for accompanying dark matter to make up the rest of the dark matter abundance. Moreover, superpartners of the axion can provide non-thermal production of supersymmetric dark matter. In this presentation, I briefly review neutralino dark matter. I also discuss the supersymmetric axion model as a natural dark matter model.
