In supersymmetry (SUSY), dark matter (DM) candidates arise naturally for either R-parity conserving and breaking models. We present a summary of the state of art of SUSY DM particles. If the neutralino, the archetype WIMP (weakly interacting massive particle), or the right-handed sneutrino is the lightest SUSY particle (LSP), they are absolutely stable and good DM candidates for R-parity conserved models. We consider one of the minimal SUSY extension that can reproduce neutrino data, and study the parameter space for both DM candidates using several public tools. On the other hand, if the gravitino or the axino (SUSY partners of graviton and axion) is the LSP, either of them can be valid non-WIMP DM candidates for both R-parity conserving and breaking models. If R-parity is broken, they can decay to a mono-energetic photon and a neutrino with lifetime longer than the age of the Universe. We study a mixture of axinos and gravitinos considering cosmological constraints, neutrino data, γ-ray observations on spectral lines from current detectors, and compute prospects for future γ-ray space missions.
