Limits on Abelian Gauge Couplings

理论基本粒子物理学和宇宙学的研究将考虑存在已知粒子之外的新粒子的可能性，这些粒子会导致已知粒子之外的新力。这样的新粒子将对天体物理学产生一系列有趣的影响。事实上，天体物理观测将用于该项目，以约束可能的新粒子的性质。许多理论表明，在这项工作中需要研究的新粒子的存在，而这项努力将是一次重要的尝试，看看可以从天体物理数据中学到什么。

Research in theoretical elementary particle physics and cosmology will consider the possibility that there exist new particles beyond those already known which lead to new forces beyond those already known. Such new particles would have a variety of interesting consequences for astrophysics. Indeed, astrophysical observations will be used in this project to constrain the properties of the possible new particles. Many theories suggest the existence of new particles of the type to be studied in this work, and the effort will be an important attempt to see what can be learned about such particles from astrophysical data.
