The Sudbury Neutrino Observatory (SNO), whose main purpose was to study the neutrinos produced in the Sun, demonstrated that neutrinos can change flavor and, thus, they are massive particles. SNO detected and recorded neutrino and cosmic ray interactions from 1999 to 2006 and several analyses have been completed in the past year using legacy data. We present the results of the most recent ones: the measurements of neutron production in atmospheric neutrino interactions and neutron production by cosmic muons, a search for Lorentz symmetry violation in neutrino oscillations and a search for neutrino decay. A few other analyses are ongoing and we comment about their goal and status.

SNO：最近的新结果

萨德伯里中微子天文台 (SNO) 的主要目的是研究太阳产生的中微子，它证明中微子可以改变味道，因此它们是大质量粒子。SNO 从 1999 年到 2006 年探测并记录了中微子和宇宙射线的相互作用，并在过去一年使用遗留数据完成了几项分析。我们展示了最近的结果：大气中微子相互作用中中子产生的测量和宇宙μ子产生的中子，中微子振荡中洛伦兹对称性破坏的研究以及中微子衰变的研究。其他一些分析正在进行中，我们评论了他们的目标和状态。
