标题： The primary protons and the atmospheric neutrino fluxes

摘要： 大气中微子事件率的预测受到显著不确定性的影响，然而SK和其他地下探测器获得的关于ν_μ和反ν_μ“消失”的证据是稳健的，在不假设非常大的人为实验系统效应的情况下，无法在最小标准模型的框架内解释这一现象。因此，超越标准模型的“新物理”存在几乎已被确立；中微子振荡对所有数据都有很好的拟合。理论不确定性在数据的详细解释和振荡参数的估计中起着重要作用。 显示英文摘要

摘要： The predictions of the atmospheric nu event rates are affected by significant uncertainties, however the evidence for the `disappearance' of nu_mu's and antinu_mu's obtained by SK and other underground detectors is robust and cannot be accounted in the framework of the minimum standard model without assuming very large ad hoc experimental systematic effects. The existence of `new physics' beyond the standard model is therefore close to be established; neutrino oscillations provide a very good fit to all data. The theoretical uncertainties do have an important role in the detailed interpretation of the data, and in the estimate of oscillation parameters.
