论文摘要
我们研究了电子和暗物质通过标量场的滚动与暗物质相互作用的模型，标量场来自额外的维理论，例如Braneworld理论和Brans-Dicke理论。在该模型中，暗能量与暗物质和电子伴侣，这会导致早期宇宙中暗物质和电子的质量能量的较大值。我们还将模型符合宇宙数据。通过分析来自普朗克的数据，Baryon声学振荡（BAO），光曲线（Pantheon）和类型 - IA Supernovae（SH0ES），可以看出，在我们的模型中可以缓解Hubble张力，并且耦合参数更喜欢非零值，具有超过2σ的显着性。
We investigate the model where electrons and dark matter interact with dark energy through the rolling of a scalar field which comes from extra dimensional theories such as the braneworld theory and Brans-Dicke theory. In this model, dark energy couples to dark matter and electrons, which leads to larger values of the mass energies of dark matter and electrons in the early universe. We also fit our model to the cosmological data. By analyzing the data from Planck, baryon acoustic oscillation (BAO), light curves (Pantheon), and type-Ia supernovae (SH0ES), it can be seen that the Hubble tension is relieved in our model and the coupling parameter prefers a non-zero value with a significance of over 2σ.
