抽象的。利用有效理论方法计算了标准模型及其最小超对称模型中中微子质量和混合的低能阈修正。我们证明，他们稳定的中微子质量和混合的规模，其中重整化群（RG）方程集成的选择方面的结果。(This证实了最近重新推导hep-ph/0108005中SM的RGE的正确性。）因为，正如我们所知，这些修正可能是非常重要的现象，我们推导出明确的公式，可以应用到特定的模型中微子质量和混合。
Abstract. We compute the low energy threshold corrections to neutrino masses and mixing in the standard model (SM) and its minimal supersymmetric version, using the effective theory technique. We demonstrate that they stabilize the results for neutrino masses and mixing with respect to the choice of the scale to which the renormalization group (RG) equation is integrated. (This confirms the correctness of the recent re-derivation of the RGE for the SM in hep-ph/0108005.) Since, as is known, those corrections are potentially very important for phenomenology we derive for them the explicit formulae that can be applied to specific models of neutrino masses and mixing.
