相互作用的3形式暗能量模型：区分相互作用和避免大撕裂的小兄弟
Interacting 3-form dark energy models: distinguishing interactions and avoiding the Little Sibling of the Big Rip
摘要：
本文考虑了在暗区具有相互作用的3-形式暗能量模型。我们的目标是区分现象的相互作用，通过暗物质（DM）和DE能量密度定义。我们主要分两个阶段进行分析。在第一阶段，我们确定了非相互作用的3-形式DE模型，它一般导致一个突然的晚时宇宙学事件，这被称为大撕裂（LSBR）的小兄弟。我们分类的相互作用，可能会避免这种晚时间的突然事件。我们还研究了与目前基于BAO和SDSS数据的研究所表明的DM和DE能量密度之间的相互作用相一致的模型的参数空间。在后一阶段，我们观察区分这些相互作用使用的状态层次参数$\{ S_{3}^{(1)}\,,\, S_{4}^{(1)}\} \,,\,\{ S_{3}^{(1)}\,,\, S_{5}^{(1)}\} .$我们还计算的增长因子参数$ε(z)$的各种相互作用，我们认为在这里，并使用复合零诊断（CND）$\{ S_{3}^{(1)}\,,\,ε(z)\} $作为一种工具，通过测量它们的偏离一致性模型来验证这些相互作用。此外，我们还结合SDSS~III最近公布的结构线性增长率的测量数据对我们的模型进行了初步分析。
英文摘要：
In this paper we consider 3-form dark energy (DE) models with interactions in the dark sector. We aim to distinguish the phenomenological interactions that are defined through the dark matter (DM) and the DE energy densities. We do our analysis mainly in two stages. In the first stage, we identify the non-interacting 3-form DE model which generically leads to an abrupt late-time cosmological event which is known as the little sibling of the Big Rip (LSBR). We classify the interactions which can possibly avoid this late-time abrupt event. We also study the parameter space of the model that is consistent with the interaction between DM and DE energy densities at present as indicated by recent studies based on BAO and SDSS data. In the later stage, we observationally distinguish those interactions using the statefinder hierarchy parameters $\{ S_{3}^{(1)}\,,\, S_{4}^{(1)}\} \,,\,\{ S_{3}^{(1)}\,,\, S_{5}^{(1)}\} .$ We also compute the growth factor parameter $ε(z)$ for the various interactions we consider herein and use the composite null diagnostic (CND) $\{ S_{3}^{(1)}\,,\,ε(z)\} $ as a tool to characterise those interactions by measuring their departures from the concordance model. In addition, we make a preliminary analysis of our model in light of the recently released data by SDSS~III on the measurement of the linear growth rate of structure.
