弱耦合SUSY破缺扇区中的暗物质和赝平坦方向

Dark Matter and Pseudo-flat Directions in Weakly Coupled SUSY Breaking Sectors

Boaz Keren-Zur, Luca Mazzucato, Yaron Oz

摘要:

我们考虑的候选人暗物质的规范介导的超对称性破缺模型,其中的超对称性破缺部门是弱耦合和可计算的。这种模型通常包含经典的平坦方向,接收几TeV的单圈质量。这些伪平坦的方向提供了一种新的机制来解释冷暗物质遗迹的丰度。我们还讨论了在这样的模型中重引力子暗物质的可能性。

英文摘要:

We consider candidates for dark matter in models of gauge mediated supersymmetry breaking, in which the supersymmetry breaking sector is weakly coupled and calculable. Such models typically contain classically flat directions, that receive one-loop masses of a few TeV. These pseudo-flat directions provide a new mechanism to account for the cold dark matter relic abundance. We discuss also the possibility of heavy gravitino dark matter in such models.
