论文摘要
我们提出了载体暗物质产生的情况,其中包含一个复杂的充气场,该电源在暗规场下被充电,并且具有对称性破坏电位。随着充气场向电势的全球最小值滚动,深色光子变得巨大,质量可能大于通货膨胀期间的哈勃尺度。产生的深色光子的量子波动的累积能量可在广泛的参数中观察到的暗物质的遗物密度。根据参数,横向模式或纵向模式或它们的组合可以产生观察到的暗物质遗物能量密度。
We present a scenario of vector dark matter production during inflation containing a complex inflaton field which is charged under a dark gauge field and which has a symmetry breaking potential. As the inflaton field rolls towards the global minimum of the potential the dark photons become massive with a mass which can be larger than the Hubble scale during inflation. The accumulated energy of the quantum fluctuations of the produced dark photons gives the observed relic density of the dark matter for a wide range of parameters. Depending on the parameters, either the transverse modes or the longitudinal mode or their combination can generate the observed dark matter relic energy density.
