US-France Cooperative Research: Dark Matter Research

这个为期三年的奖项支持美国和法国在天体物理学方面的合作研究，合作对象是加州大学伯克利分校的美国国家科学基金会粒子天体物理学科学与技术（STC）和法兰西学院的体质微粒实验室。美国和法国研究组分别由伯克利大学STC主任Bernard Sadoulet和法国研究组组长Yannick Giraud-Heraud领导。具体来说，将为伯克利STC附属的美国高级研究生和博士后研究人员前往法国提供支持。美国和法国的团队将把重点放在暗物质的基本问题上，这是天体物理学研究中最优先考虑的课题。有证据表明，90%或更多的宇宙是由暗物质组成的，这些物质可能以粒子的形式存在，可以追溯到宇宙的起源。暗物质问题的研究对于理解宇宙的起源和物质的基本性质具有重要的意义。在这个项目中，美国和法国的团队将对暗物质进行实验搜索，要么以弱相互作用粒子的形式，要么以大质量天体物理致密晕物体的形式。

This three-year award supports U.S.-France cooperative research in astrophysics between the NSF Science and Technology (STC) for Particle Astrophysics at the University of California, Berkeley, and the Laboratoire de Physique Corpusculaire at the College de France. The U.S. and French research teams are led by Bernard Sadoulet, Director of the STC at Berkeley, and Yannick Giraud-Heraud, leader of the French group. Specifically, support will be provided to advanced U.S. graduate students and postdoctoral researchers affiliated with the Berkeley STC for their travel to France. The U.S. and French teams will focus on the fundamental problem of dark matter, a topic identified as the highest priority in astrophysics research. Evidence indicates that 90% or more of the Universe is made of dark matter, and that this matter may be in the form of particles dating back to the beginning of the Universe. The study of the dark matter problem has important implications for understanding the origin of the Universe and the fundamental nature of matter. In this project, the U.S. and French teams will perform experimental searches for dark matter either in the form of weakly interactive particles or in the form of massive astrophysical compact halo objects.
