相互作用能量分量和观测$H(z)$数据

Interacting Energy Components and Observational $H(z)$ Data

Hao Wei, Shuang Nan Zhang

摘要:

在本说明中,我们扩展了我们以前的工作[物理。B 644,7(2007),astro-ph/0609597],并比较11个相互作用的暗能量模型与观测$H(z)$数据的不同耦合。然而,这些模型中没有一个比最简单的$Λ$ CDM模型好。这意味着,在暗能量和尘埃物质相互作用的宇宙学模型中,要么需要更多的奇异耦合,要么{ \em根本没有相互作用}。我们认为这一结果对文献中广泛研究的相互作用暗能量模型是不利的。

英文摘要:

In this note, we extend our previous work [Phys. Lett. B 644, 7 (2007), astro-ph/0609597], and compare eleven interacting dark energy models with different couplings to the observational $H(z)$ data. However, none of these models is better than the simplest $Λ$CDM model. This implies that either more exotic couplings are needed in the cosmological models with interaction between dark energy and dust matter, or {\em there is no interaction at all}. We consider that this result is disadvantageous to the interacting dark energy models studied extensively in the literature.
