摘要：

我们研究了大质量电动力学的宇宙学，并探讨了大质量光子能否解释暗能量的可能性。该作用量由引力的标量-矢量-张量理论给出，该理论是通过大质量Stueckelberg QED与引力的非最小耦合得到的，并且通过特别注意光子质量的作用来研究其宇宙学后果。我们发现，该理论允许宇宙学演化的辐射和物质占主导地位的时代是由一个长期的几乎恒定的暗能量，密切模仿$Λ$ CDM模型和电流加速的主要来源是由非零光子质量由关系$Λ\sim m^2$。详细的数值分析表明，$\sim 10^{-34}$ eV量级的非零光子质量与目前的观测结果是一致的。这个量级远小于目前对光子质量的最严格限制，即$m \leq 10^{-27}$ eV的量级。

英文摘要：

We investigate cosmology of massive electrodynamics and explore the possibility whether massive photon could provide an explanation of the dark energy. The action is given by the scalar-vector-tensor theory of gravity which is obtained by non-minimal coupling of the massive Stueckelberg QED with gravity and its cosmological consequences are studied by paying a particular attention to the role of photon mass. We find that the theory allows cosmological evolution where the radiation- and matter-dominated epochs are followed by a long period of virtually constant dark energy that closely mimics $Λ$CDM model and the main source of the current acceleration is provided by the nonvanishing photon mass governed by the relation $Λ\sim m^2$. A detailed numerical analysis shows that the nonvanishing photon mass of the order of $\sim 10^{-34}$ eV is consistent with the current observations. This magnitude is far less than the most stringent limit on the photon mass available so far, which is of the order of $m \leq 10^{-27}$eV.
