论文摘要
我们简短地讨论了中微子-4实验结果以及寻找无菌中微子的其他实验的结果。我们估计了无菌中微子对参数的贡献$δm^2_ {14} = 7.3 \ text {ev}^2 $和$ \ sin^22θ_{14} = 0.36 = 0.36 $在中微子-4在宇宙能量密度的实验中获得。我们解决了测得的无菌中微子参数与宇宙学无菌中微子的约束之间的矛盾。在本文中，我们希望引起人们对实验与理论之间矛盾的问题的关注，以激发人们对几个EV区域中质量的无菌中微子的搜索，以及有必要充分提高实验的精度。
We present a short discussion of the Neutrino-4 experimental results and the results of other experiments searching for the sterile neutrino. We estimated the contribution of the sterile neutrino with parameters $Δm^2_{14} = 7.3\text{eV}^2$ and $\sin^2 2θ_{14} = 0.36$ obtained in the Neutrino-4 experiment to the energy density of the Universe. We address the contradiction between the measured sterile neutrino parameters and the constraints on the sterile neutrino from cosmology. With this article, we want to draw attention to the problem of the contradiction between experiment and theory, in order to inspire the search for theoretical models that include a sterile neutrino with mass in the region of several eV, and to the necessity to sufficiently increase the precision of the experiment.
