Multi-faceted approach on elementary particles from accelerators, space, and underground

我们开发了一种新的分析技术，用于在大型强子对撞机等加速器实验中确定粒子的自旋，而不需要对基本模型进行理论假设。这项技术应适用于Tevatron和LEP-II的现有数据。我们用卡姆兰德实验更精确地确定了中微子参数，并给出了θ13的间接暗示，这是唯一有待测量的混合角。通过对太空的观察，我们发布了有史以来最大的宇宙图像，它覆盖了超过三分之一的天球，像素超过1万亿。在解决这三个方面的共同问题时，我们发现了一种新的机制，可以提高我们银河系中暗物质粒子的湮灭几率，并指出了在地下中微子探测器中找到证据的可能性。

We developed a novel analysis technique to determine the spin of particles at accelerator experiments such as LHC which is free from theoretical assumptions about the underlying models. This technique should be applicable to existing data from Tevatron and LEP-II. We determined the neutrino parameters more precisely with the KamLAND experiment, and showed indirect hints for θ13, the only mixing angle yet to be measured. With observation of space, we released the largest image of the Universe ever, which covers more than a third of the celestial sphere with more than a trillion pixels. In addressing the common problem in these three, we discovered a new mechanism that enhances the annihilation probability of dark matter particles in our galaxy, and pointed out the possibility to find its evidence in underground neutrino detectors.
