测量2-3轻子混合与最大值D23 <$1/2−sin 2 <$23的偏差是理解中微子质量和混合起源的关键问题之一。在3 π背景下，我们研究了大气中微子中各种观测量对D ~（23）的依赖性。我们对大气和反应堆中微子数据进行了全局3 π分析，同时考虑了“太阳”参数（μ m 2和μ 12）驱动的振荡和1-3混合的影响。从一个主导的质量尺度近似的偏离导致了
The measurement of the deviation of the 2-3 leptonic mixing from maximal, D23 ≡ 1/2−sin 2 �23, is one of the key issues for understanding the origin of the neutrino masses and mixing. In the 3� context we study the dependence of various observables in the atmospheric neutrinos on D23. We perform the global 3�-analysis of the atmospheric and reactor neutrino data taking into account the effects of both the oscillations driven by the “solar” parameters (�m 2 and �12) and the 1-3 mixing. The departure from the one–dominant mass scale approximation results into the shift of
