AI 中文摘要
我们提出了在暴胀期间通过多矢量凝聚体的失准机制，经动力学耦合产生暗物质。我们施加各向同性化背景矢量场以使模型摆脱各向异性的严格约束。然而，结果表明，无论涨落在弱混合还是强混合 regime 中，非高斯性和等曲率涨落所施加的约束相互不兼容。
英文摘要
We present dark matter production by the misalignment mechanism of a multi-vector condensate through kinetic coupling during inflation. We impose isotropized background vector fields to release the model from the stringent constraint of anisotropy. However, it turns out that the constraints imposed by non-Gaussianity and isocurvature fluctuations are incompatible with each other, regardless of whether the fluctuations are in the weak-mixing or strong-mixing regime.
