论文摘要
我们详细研究了光无菌中微子在解释长基线实验的最新数据中的影响，而不是$ν$ A和T2K，评估了标准3型风味参数估计值的鲁棒性/脆弱性相对于3+1方案中引起的扰动的估计值。我们发现，3味分析的所有基本特征，包括弱指示（$ \ sim $ 1.4 $σ$），有利于倒数中微子的质量顺序，偏爱CP相$δ_{13} \ sim1.2π$的值，以及两个of $ fiver的$ fiver unter的$ fiver untermate of $ quenter的本质;我们的分析还表明，有可能在新的CP相$δ_{14} $上获得一些约束。最后，我们指出的是，与非标准的中微子相互作用不同，光无菌中微子无法减轻外观渠道中NO $ν$ A和T2K之间出现的紧张局势。
We study in detail the impact of a light sterile neutrino in the interpretation of the latest data of the long baseline experiments NO$ν$A and T2K, assessing the robustness/fragility of the estimates of the standard 3-flavor parameters with respect to the perturbations induced in the 3+1 scheme. We find that all the basic features of the 3-flavor analysis, including the weak indication ($\sim$1.4$σ$) in favor of the inverted neutrino mass ordering, the preference for values of the CP-phase $δ_{13} \sim 1.2π$, and the substantial degeneracy of the two octants of $θ_{23}$, all remain basically unaltered in the 4-flavor scheme. Our analysis also demonstrates that it is possible to attain some constraints on the new CP-phase $δ_{14}$. Finally, we point out that, differently from non-standard neutrino interactions, light sterile neutrinos are not capable to alleviate the tension recently emerged between NO$ν$A and T2K in the appearance channel.
