摘要：

本文研究了最近提出的沼泽地猜想在再加热约束下对暴胀模型的唯象结果。如果假设暗物质是在再加热过程中产生的，该猜想将通过其当前的遗迹丰度对暗物质参数空间提供进一步的约束。正如我们已经指出的和本文所分析的那样，任何成功的暴胀情景都明显地与上述猜想处于紧张状态。然而考虑到沼泽地参数是自由的并受暴胀观测量的约束，我们详细研究了它对再加热和暗物质现象的影响。我们指出沼泽地猜想和普朗克在当前$2 σ$范围内的标量谱指数$n_s$之间的联系，以及对再加热温度和暗物质湮灭截面施加的相关约束。

英文摘要：

In this paper, we studied the phenomenological consequences of recently proposed swampland conjecture on the inflationary models though constraints on reheating. If dark matter is assumed to be produced during reheating, the conjecture will provide further constraints on the dark matter parameter space through its current relic abundance. As has been pointed out already and also analyzed in our present paper any successful inflationary scenario is in clear tension with the aforementioned conjecture in its current form. However considering the swampland parameters to be free and constrained by the inflationary observables, we studied in detail its consequence on the reheating and dark matter phenomenology. We point out the connection between swampland conjecture and the scalar spectral index $n_s$ by PLANCK within current $2 σ$ range, and associated constraints imposed on the reheating temperature and the dark matter annihilation cross-section.
