论文摘要
尽管宇宙微波背景（CMB）是中微子质量最强大的宇宙学探测器，但它与$ H_0 $的本地直接测量遇到麻烦，这称为$ H_0 $张力。由于中微子质量与CMB中的$ H_0 $相关，因此人们可以期望宇宙学对中微子群众的界限会受到$ H_0 $张力的影响。我们通过假设具有修改后的重组模型来研究这种张力会影响这种张力对中微子质量的影响，该模型已被证明可以解决张力。我们认为，在可以解决$ h_0 $张力的模型中，对中微子质量的约束变得明显较弱。
Although cosmic microwave background (CMB) is the most powerful cosmological probe of neutrino masses, it is in trouble with local direct measurements of $H_0$, which is called the $H_0$ tension. Since neutrino masses are correlated with $H_0$ in CMB, one can expect the cosmological bound on neutrino masses would be much affected by the $H_0$ tension. We investigate what impact this tension brings to cosmological bound on neutrino masses by assuming a model with modified recombination which has been shown to resolve the tension. We argue that constraints on neutrino masses become significantly weaker in models where the $H_0$ tension can be resolved.
