标题： Phenomenology of atmospheric neutrinos

摘要： 对于解决大气中微子问题而言，关于向上运动的μ子的数据的相关性得到了强调。 特别是，它们包含在分析中证实了中微子振荡假说的正确性，并允许排除一些其他奇特的解释，例如中微子衰变、味改变中性流、等效原理的破坏（至少在其最简单形式中），并且由于物质效应的差异，原则上能够区分不同的中微子振荡模型（nu_mu <-> nu_tau 与 nu_mu <-> nu_s）。 显示英文摘要

摘要： The relevance of the data concerning upward--going muons for the solution of the atmospheric neutrino problem is stressed. In particular, their inclusion in the analysis confirms the goodness of the neutrino oscillation hypothesis and allows to exclude some alternative, exotic explanations such as neutrino decay, flavour changing neutral currents, violations of the equivalence principle (at least in their simplest forms), and also to discriminate, in principle, between different neutrino oscillation models (nu_mu <-> nu_tau versus nu_mu <-> nu_s), because of the difference in the matter effects.
