论文摘要
反对称张量场（两种形式场）是字符串理论中无处不在的组成部分，通常通过其动力学项与标量扇区伴侣。在本文中，我们提出了一种宇宙学的情况，即两种形式场的产生是由耦合充气场的背景运动触发的，发生在通货膨胀的中间阶段，并在通货膨胀后产生相当数量的原始黑洞作为暗物质。我们还计算通过曲率扰动来源的二级引力波，并表明所得功率光谱是可以通过未来的空间激光干涉仪测试的。
Antisymmetric tensor field (two-form field) is a ubiquitous component in string theory and generally couples to the scalar sector through its kinetic term. In this paper, we propose a cosmological scenario that the particle production of two-form field, which is triggered by the background motion of the coupled inflaton field, occurs at the intermediate stage of inflation and generates the sizable amount of primordial black holes as dark matter after inflation. We also compute the secondary gravitational waves sourced by the curvature perturbation and show that the resultant power spectra are testable with the future space-based laser interferometers.
