AI 中文摘要
我们在爱因斯坦-温伯格-萨拉姆理论中构造了玻色子星，即电弱标准模型的玻色子扇区与爱因斯坦引力理论的最小耦合。这些构型处处正则、球对称且渐近平坦，由大质量$W$和$Z$玻色子的静态凝聚体组成，其质量源于希格斯机制。尽管相应的场在自然界中存在，但在物理电弱尺度下引力效应可忽略，且这些构型将是微观的。因此，我们将牛顿常数和电弱质量比保持在其物理值，将该模型解释为具有截然不同能量尺度的\textit{暗}电弱理论的玻色子扇区。选择超轻矢量玻色子质量$m_{\mathrm{W}}c^{2}=8.7\times10^{-13}\\,$eV（如GW190521的Proca星解释所建议），我们的玻色子星可以达到中等质量黑洞范围的质量。
英文摘要
We construct bosonic stars in the Einstein-Weinberg-Salam theory, namely the bosonic sector of the electroweak Standard Model minimally coupled to Einstein's theory of gravity. These configurations are everywhere regular, spherically symmetric and asymptotically flat, consisting of a static condensate of the massive $W$ and $Z$ bosons, whose masses arise from the Higgs mechanism. Although the corresponding fields exist in nature, gravitational effects are negligible at the physical electroweak scale and the configurations would be microscopic. Keeping Newton's constant and the electroweak mass ratios at their physical values, we therefore interpret the model as the bosonic sector of a \textit{dark} electroweak theory with a radically different energy scale. Choosing the ultralight vector boson mass $m_{\mathrm{W}}c^{2}=8.7\times10^{-13}\,$eV, as suggested by the Proca star interpretation of GW190521, our bosonic stars can attain masses in the intermediate-mass black hole range.
