我们用四种不同的超对称计算程序比较了最小超引力模型(MSUGRA)中中性微子暗物质的遗迹密度。虽然对中性子遗迹密度的预测在mSUGRA空间的大部分区域都相当稳定，但在最有物理意义的区域可以观察到巨大的差异，特别是焦点、大Tan和湮灭区域。
We compare the relic density of neutralino dark matter within the minimal supergravity model (mSUGRA) using four different public codes for supersymmetric spec- tra evaluation. While the predictions for the relic density of neutralinos are rather stable in most of the mSUGRA space, it is in the most physically interesting regions that large discrepancies can be observed, in particular the focus point, large tanand coannihilation regions.
