除了LSND异常外，目前的中微子数据可以用一个3×3混合矩阵的框架来描述，这个混合矩阵介于风味特征态ν e、νµ和ν τ和质量特征态ν 1、ν 2和ν 3之间。（见B. Kayser的Review“Neutrino Mass, Mixing and Flavor Change”公式（13.31）。）清单分为以下几部分：(A)中微子通量和事件比：显示了与加速器、反应堆、大气和太阳中微子实验的各种振荡测试相对应的测量结果。通常，比率涉及对振荡敏感领域的测量，与预期没有振荡影响的领域进行比较。(B)三个中微子混合参数：显示了sin 2 (2θ 12), sin 2 (2θ 23),∆m 2 21，∆m 2 32的测量值，以及sin 2 （2θ 13）的极限，这些都是基于“中微子质量，混合和风味变化”综述中描述的三种中微子混合方案的数据解释。“(C)其他中微子混合结果：显示可能与LSND振荡主张有关的实验振荡概率的测量和限制。包括对νµ→ν e，¯νµ→¯ν e，无菌中微子和CPT测试敏感的实验。(A)中微子通量和事件比(A)中微子通量和事件比(A)中微子通量和事件比(A)中微子通量和事件比(A)中微子通量和事件比加速器νµ实验中观测到的/预期的事件。加速器νµ实验中的事件（观察到的/预期的）。加速器νµ实验中的事件（观察到的/预期的）。加速器νµ实验中的事件（观察到的/预期的）。有些中微子振荡实验比较两个或多个探测器中的通量。这通常被引用为在没有振荡的情况下，远端探测器中的事件率与基于近端探测器外推的期望率之比。
With the exception of the LSND anomaly, current neutrino data can be described within the framework of a 3×3 mixing matrix between the flavor eigenstates ν e , ν µ , and ν τ and the mass eigenstates ν 1 , ν 2 , and ν 3. (See Eq. (13.31) of the Review " Neutrino Mass, Mixing and Flavor Change " by B. Kayser.) The Listings are divided into the following sections: (A) Neutrino fluxes and event ratios: shows measurements which correspond to various oscillation tests for Accelerator, Reactor , Atmospheric, and Solar neutrino experiments. Typically ratios involve a measurement in a realm sensitive to oscillations compared to one for which no oscillation effect is expected. (B) Three neutrino mixing parameters: shows measurements of sin 2 (2θ 12), sin 2 (2θ 23), ∆m 2 21 , ∆m 2 32 , and limits for sin 2 (2θ 13) which are all interpretations of data based on the three neutrino mixing scheme described in the review " Neutrino Mass, Mixing and Flavor Change. " (C) Other neutrino mixing results: shows measurements and limits for the probability of oscillation for experiments which might be relevant to the LSND oscillation claim. Included are experiments which are sensitive to ν µ → ν e , ¯ ν µ → ¯ ν e , sterile neutrinos, and CPT tests. (A) Neutrino fluxes and event ratios (A) Neutrino fluxes and event ratios (A) Neutrino fluxes and event ratios (A) Neutrino fluxes and event ratios Events (observed/expected) from accelerator ν µ experiments. Events (observed/expected) from accelerator ν µ experiments. Events (observed/expected) from accelerator ν µ experiments. Events (observed/expected) from accelerator ν µ experiments. Some neutrino oscillation experiments compare the flux in two or more detectors. This is usually quoted as the ratio of the event rate in the far detector to the expected rate based on an extrapolation from the near detector in the absence of oscillations.
