论文摘要
从De Broglie - Proca Lagrangian开始，用于大规模的矢量场，我们计算了通货膨胀期间引力颗粒产生（GPP）引起的颗粒的数量密度，并详细考虑了通过重新加热的数量密度的演变。我们发现可见的场景是生产宽度范围内的深色暗物质，低至微型电子伏特至$ 10^{14} $ GEV。引力颗粒的产生不取决于深色光子与标准模型颗粒的任何耦合。
Starting with the de Broglie--Proca Lagrangian for a massive vector field, we calculate the number density of particles resulting from gravitational particle production (GPP) during inflation, with detailed consideration to the evolution of the number density through the reheating. We find plausible scenarios for the production of dark-photon dark matter of mass in a wide range, as low as a micro-electron volt to $10^{14}$ GeV. Gravitational particle production does not depend on any coupling of the dark photon to standard-model particles.
