论文摘要
我们探索了一种在具有标准模型的多个隐藏扇区但具有不同HIGGS质量参数的模型中产生Baryon不对称和暗物质的机制。如果负责重新加热标准模型和外来部门的领域具有不对称性，则可以使用标准的Sphaleron工艺将其转换为Baryon不对称性。带有正质量平方的隐藏扇形可以使用其重子不对称来容纳暗物质，而相对于Baryons的深色物质较大，这是由于深色Sphaleons一直活跃在隐藏的扇区QCD量表上。这种情况预测，暗物质聚集在大的深色核中，并在有效的相对论自由度上给出了下限，$Δn_{\ rm eff} \ gtrsim 0.05 $，可以在下一代COSMIC Microhave背景实验CMB-S4中观察到。
We explore a mechanism for producing the baryon asymmetry and dark matter in models with multiple hidden sectors that are Standard-Model-like but with varying Higgs mass parameters. If the field responsible for reheating the Standard Model and the exotic sectors carries an asymmetry, it can be converted into a baryon asymmetry using the standard sphaleron process. A hidden sector with positive Higgs mass squared can accommodate dark matter with its baryon asymmetry, and the larger abundance of dark matter relative to baryons is due to dark sphalerons being active all the way down the hidden sector QCD scale. This scenario predicts that dark matter is clustered in large dark nuclei and gives a lower bound on the effective relativistic degrees of freedom, $ΔN_{\rm eff} \gtrsim 0.05$, which may be observable in the next-generation cosmic microwave background experiment CMB-S4.
