Most of these papers generally exclude regions in the $\mathit M_{2}~-~{{\mathit \mu}}$ parameter plane by requiring that the ${{\widetilde{\mathit \chi}}_{{{1}}}^{0}}$ contribution to the overall cosmological density is less than some maximal value to avoid overclosure of the Universe. Those not based on the cosmological density are indicated. Many of these papers also include LEP and/or other bounds.

Mass of the higgsino (=LSP) is limited to ${\mathit m}_{{{\widetilde{\mathit H}}}}{ {}\lesssim{} }$ $3.2$ TeV. 49  KRAUSS 1983 finds ${\mathit m}_{{{\widetilde{\mathit \gamma}}}}$ not 30 eV to 2.5 GeV. KRAUSS 1983 takes into account the gravitino decay. Find that limits depend strongly on reheated temperature. For example a new allowed region ${\mathit m}_{{{\widetilde{\mathit \gamma}}}}$ = 4$-$20 MeV exists if ${\mathit m}_{\mathrm {gravitino}}$ $<$40 TeV. See figure 2.
