论文摘要

可以在各种中微子实验中探测大额外维度的存在。我们在具有较大额外尺寸的模型中分析了几个中微子数据集。我们表明,可以用大型额外尺寸引起的中微子振荡来解释包膜异常,但是甘露异常首选的参数空间区域与反应器速率数据的边界以及Daya Bay和Minos的数据呈张力。我们还提出了从Katrin数据分析获得的界限。我们表明,当前的实验可以对额外维度的$ r _ {\ text {ed}} $的尺寸进行强界限:$ r _ {\ text {ed}} <0.20〜μ \ text {m} $ \ text {m} $分别用于标准中微子质量的正常和倒下。

The existence of Large Extra Dimensions can be probed in various neutrino experiments. We analyze several neutrino data sets in a model with a dominant large extra dimension. We show that the Gallium anomaly can be explained with neutrino oscillations induced by the large extra dimension, but the region of parameter space which is preferred by the Gallium anomaly is in tension with the bounds from reactor rate data, as well as the data of Daya Bay and MINOS. We also present bounds obtained from the analysis of the KATRIN data. We show, that current experiments can put strong bounds on the size $R_{\text{ED}}$ of the extra dimension: $R_{\text{ED}} < 0.20~μ\text{m}$ and $R_{\text{ED}} < 0.10~μ\text{m}$ at 90\% C.L. for normal and inverted ordering of the standard neutrino masses, respectively.
