Signatures, for and tests of, extensions of the Standard Model of particle physics at the Large Hadron Collider

大型强子对撞机(LHC)将于明年某个时候在欧洲核子研究中心开始运行。从那时起，大型强子对撞机实验将在十年或更长的时间里主宰“能源前沿”。为了从大型强子对撞机及其实验的巨大投资中获得最大的科学回报，需要国际上的协调努力。在这个项目中，我们将分析大型强子对撞机粒子物理标准模型扩展的签名和测试。这包括开发新的方法来检测新的粒子，以及开发新的方法来提取这些理论中迄今未知的参数。至少在一开始，我们的主要关注点将放在超对称性轻微破缺的理论上，这些理论目前被认为最有可能代表自然。当然，一旦有了真正的大型强子对撞机数据，我们将专注于任何仍然可行的情景。我们打算与巴西顶尖的对撞机物理学家合作完成这项工作。

The Large Hadron Collider (LHC) will commence operations at CERN sometime next year. From then on LHC experiments will dominate the “energy frontier” for a decade or more. In order to maximize the scientific return from the very large investment made in the LHC and its experiments, coordinated international efforts are needed. In this project we will analyse signatures for, and tests of, extensions of the Standard Model of particle physics at the LHC. This includes the development of novel methods to detect new particles, and of novel methods to extract the as yet unknown parameters of these theories. At least initially our main focus will be on theories with softly broken supersymmetry, which are currently considered to be most likely to represent Nature. Of course, once real LHC data are at hand, we will focus on whatever scenario remains viable. We intend to do this in collaboration with the top collider physicists in Brazil.
