论文摘要
我们讨论了通过深色光子场和充气之间的耦合产生浅暗光子暗物质的可能性。由于通货膨胀期间的充气运动，具有较大波长的深色光子有效产生，并且在物质辐射平等的时间之前变为非依赖性。我们通过分析计算生产量。正确的遗物丰度是通过深色光子质量延伸到$ 10^{ - 21} \，\ rm eV $的。
We discuss the possibility of producing a light dark photon dark matter through a coupling between the dark photon field and the inflaton. The dark photon with a large wavelength is efficiently produced due to the inflaton motion during inflation and becomes non-relativistic before the time of matter-radiation equality. We compute the amount of production analytically. The correct relic abundance is realized with a dark photon mass extending down to $10^{-21} \, \rm eV$.
