Limits on Abelian Gauge Couplings

理论基本粒子物理学和宇宙学的研究将考虑在已知粒子之外存在新粒子的可能性，这些新粒子导致比已知粒子更大的新力。这样的新粒子将对天体物理学产生各种有趣的后果。事实上，这个项目将使用天体物理观测来限制可能的新粒子的性质。许多理论表明，这项工作中将研究这种类型的新粒子的存在，而这一努力将是一次重要的尝试，试图从天体物理数据中了解到关于这种粒子的信息。

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.
