论文摘要

描述暗物质与暗能量之间非重力相互作用的宇宙学模型基于暗物质和暗能量之间相互作用速率的某些现象学选择。没有这样的指导规则可以选择这种互动速率。 {\it In the present work we show that various phenomenological models of the interaction rates might have a strong field theoretical ground.} We explicitly derive several well known interaction functions between dark matter and dark energy under some special conditions and finally constrain them using the latest cosmic microwave background observations from final Planck legacy release together with baryon acoustic oscillations distance measurements.我们的分析报告说,其中一种交互功能能够减轻$ H_0 $张力。我们还针对$λ$ CDM模型进行了所有模型的贝叶斯证据分析。从贝叶斯的证据分析中,尽管参考方案比相互作用的方案优选,但是,我们发现两个相互作用的模型接近参考$λ$ CDM模型。

Cosmological models describing the non-gravitational interaction between dark matter and dark energy are based on some phenomenological choices of the interaction rates between dark matter and dark energy. There is no such guiding rule to select such rates of interaction. {\it In the present work we show that various phenomenological models of the interaction rates might have a strong field theoretical ground.} We explicitly derive several well known interaction functions between dark matter and dark energy under some special conditions and finally constrain them using the latest cosmic microwave background observations from final Planck legacy release together with baryon acoustic oscillations distance measurements. Our analyses report that one of the interacting functions is able to alleviate the $H_0$ tension. We also perform a Bayesian evidence analyses for all the models with reference to the $Λ$CDM model. From the Bayesian evidence analyses, although the reference scenario is preferred over the interacting scenarios, however, we found that two interacting models are close to the reference $Λ$CDM model.
