论文摘要
我们讨论了两种可能的情况，即弯曲机制和暗物质密度调制，其中可以增强和观察到由重力产生的超重力暗物质的非高西质信号。在这两种情况下，超重的暗物质伴侣伴随着一个额外的光场作为调解人。在衍生耦合的情况下，光场引起的产生的非高斯性可能很大，这可以为这些超重的暗物质情景提供通货膨胀证据。
We discuss two possible scenarios, namely the curvaton mechanism and the dark matter density modulation, where non-Gaussianity signals of superheavy dark matter produced by gravity can be enhanced and observed. In both scenarios, superheavy dark matter couples to an additional light field as a mediator. In the case of derivative coupling, the resulting non-Gaussianities induced by the light field can be large, which can provide inflationary evidences for these superheavy dark matter scenarios.
