论文摘要
我们认为，宇宙中大多数暗物质由原始起源的黑洞组成的可能性。我们确定了这种黑洞可能起源于以四分之一多项式电位为特征的单场通货膨胀模型的条件。我们还探索了高维操作员的效果。大型黑洞丰度所需的曲率扰动的较大功率光谱相当大的二阶张量扰动。原始引力波的产生随机背景可以由未来的空间天文台Lisa和decigo或 - 只要我们放弃暗物质连接（通过地面的高级Ligo-Virgo检测器网络）。
We consider the possibility that the majority of dark matter in our Universe consists of black holes of primordial origin. We determine the conditions under which such black holes may have originated from a single-field model of inflation characterized by a quartic polynomial potential. We also explore the effect of higher-dimensional operators. The large power spectrum of curvature perturbations that is needed for a large black hole abundance sources sizable second order tensor perturbations. The resulting stochastic background of primordial gravitational waves could be detected by the future space-based observatories LISA and DECIGO or --as long as we give up on the dark matter connection--by the ground-based Advanced LIGO-Virgo detector network.
