摘要:

本文研究了在长基线中微子实验中确定中微子混合角$θ_{23}$的八分圆,即是$θ_{23}> 45^\circ$还是$θ_{23}<45^\circ$的可能性。在这里,我们数值推导出的灵敏度范围内,这些实验可以确定,通过测量的概率的$ν_μ\to ν_{e}$过渡,八分圆的$θ_{23}$与$5σ$的确定性。分析了CP破坏角$δ$对这些极限的影响,以及束流的中微子和反中微子模的基线长度和运行时间比的影响。

英文摘要:

We study the possibility of determining the octant of the neutrino mixing angle $θ_{23}$, that is, whether $θ_{23}> 45^\circ$ or $θ_{23}<45^\circ$, in long baseline neutrino experiments. Here we numerically derived the sensitivity limits within which these experiments can determine, by measuring the probability of the $ν_μ\to ν_{e}$ transitions, the octant of $θ_{23}$ with a $5σ$ certainty. The interference of the CP violation angle $δ$ with these limits, as well as the effects of the baseline length and the run-time ratio of neutrino and antineutrino modes of the beam have been analyzed.
