Vector dark matter production during inflation in the gradient-expansion formalism

本文将梯度展开形式推广至有质量矢量场的纵向极化，构建了描述暴胀期间矢量暗物质非线性产生及反作用的耦合方程组，并揭示了在 Ratra 型耦合下，动能耦合与质量耦合的相对强弱如何决定横向与纵向极化分量对能量密度的主导贡献及系统是否进入强反作用区域。

Effects of dark dipole radiation on eccentric supermassive black hole binary inspirals

该论文研究了暗标量或矢量场通过激发偏心率超大质量黑洞双星系统的偶极辐射来加速其并合的机制，发现虽然这种辐射不足以完全解决“最后秒差距”问题，但会改变随机引力波背景的低频谱特征，且基于脉冲星计时阵列数据的贝叶斯分析支持了这一简化模型。

该论文改进了标准模型下稀有 $Z$ 玻色子衰变为重矢量夸克偶素加轻子对（ $Z\to V\ell^+\ell^-$ ）的理论预测，指出对于粲偶素末态电磁碎裂过程占主导，而对于底偶素末态其他费曼图的贡献可使分支比增加 4% 至 9%，且末态轻子的前后不对称性在标准模型中为零，这为未来利用大量 $Z$ 玻色子事例检验标准模型及其扩展提供了理论依据。
