论文摘要
我们认为，可以使用相互作用的标量特性分布来证明一般相对论中的宇宙加速度。这种相互作用是Yukawa的性质，它可以随着宇宙时间驱动费米的密度腐烂。模型的一致性是通过（a）OM（z）参数的概括，宇宙的当前物质密度对比度以及（b）使用Markov Chain Monte Carlo Code的观察数据的比较。还讨论了统一宇宙扩张历史的简单模型。在不止一次的情况下，宇宙经历了随后的宇宙扩张模式不同的时期之间的过渡。这些模式对标量 - 弗拉米式相互作用曲线以及整体宇宙学动力学施加了一些约束。
We argue that an interacting scalar-fermion distribution can be used to demonstrate the cosmic acceleration in General Relativity. The interaction is of Yukawa nature and it drives the fermion density to decay with cosmic time. The consistency of the model is established through, (a) a generalization of the Om(z) parameter, the present matter density contrast of the universe, and (b) a comparison of theoretical results with observational data, using a Markov Chain Monte Carlo code. A simple model of unified cosmic expansion history is also discussed. There are more than one instances where the universe goes through a transition between subsequent epochs with different patterns of cosmic expansion. These patterns impose some constraints on the scalar-fermion interaction profile and on the overall cosmological dynamics.
