标题： Cosmological bound on neutrino masses in the light of $H_0$ tension

摘要： 尽管宇宙微波背景（CMB）是探测中微子质量的最强有力的宇宙学探针，但它与局部直接测量的$H_0$存在冲突，这被称为$H_0$张力。 由于中微子质量与 CMB 中的$H_0$相关，在 CMB 中对中微子质量的宇宙学限制可能会受到$H_0$张力的严重影响。 我们通过假设一个修改了复合过程的模型来研究这种张力对中微子质量宇宙学限制的影响，已知该模型可以解决张力问题。 我们指出，在能够解决$H_0$张力的模型中，对中微子质量的限制会显著减弱。 显示英文摘要

摘要： 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.
