G. A. Kozlov

AI总结:

本研究探讨了弱相互作用标量暗物质与标准模型场如何构成标量玻色子星,分析了其在引力最小耦合下的宏观束缚态形成机制及有限温度下的热动力学描述。

摘要:

我们研究了弱相互作用暗物质与标准模型场之间的相互作用,其中前者与后者共同构成了玻色子宇宙学天体——标量玻色子星(BS)。标量暗物质(SDM)大质量场在与引力(GR)最小耦合时,能够形成宏观的标量束缚态。该星体可能具有近似稳态的形式及渐近平坦的几何结构,且BS的最大质量大于太阳质量。我们考虑了一个更完整模型的有效描述,该描述涉及有限温度下BS的(热)动力学势。BS的形成也可以通过隐藏矢量场的电通量来解释,这些电通量在SDM场作为与GR最小耦合的宇宙学动力学量的影响下产生。SDM场可能随温度波动,并在某个弱背景尺度下围绕平衡态建立。

英文摘要:

We study the feebly interacting dark matter with the Standard Model fields, where the preceding and the latter ones are the constituents of the bosonic cosmological objects, the scalar boson stars (BS). The scalar dark matter (SDM) massive fields can form the macroscopic scalar bound state when minimally coupled to gravity (GR). The star may have approximately a stationary form with an asymptotically flat geometry, and the maximal mass of the BS is larger than the solar mass. We consider an effective description of a more complete model with the (thermo)dynamic potential of the BS at finite temperature. The formation of the BS may also be explained in terms of the electric fluxes of the hidden vector field under the influence of the SDM field as the cosmological dynamical quantity minimally coupled to GR. The SDM fields may fluctuate with the temperature and is established around the equilibrium state at some weak background scale.
