The Large Hadron Collider will search for new symmetries and forms of matter. In particular, the LHC will look for supersymmetry , which associates particles with differing intrinsic spin angular momentum. Supersymmetry seems essential to understanding important aspects of particle physics, such as the unification of forces and dark matter. It is also a requirement of superstring theory and a fundamental ingredient in quantum gravitation. If supersymmetry is discovered, it will be accompanied by a large number of new particles, called superpartners. Their existence and properties will be determined at the LHC. Astrophysical observations are also entering a new era. Imaging of the cosmic microwave background by the WMAP and Planck satellites will provide detailed information about the early universe and the origin of cosmic structure. Precision probes of the properties of dark energy and dark matter will be provided by the proposed JDEM and LSST experiments. In addition, LIGO and LISA will measure gravitational waves. All of these astrophysical phenomenon fundamentally probe the theory of gravitation and some, like dark matter, are potentially related to supersymmetry. Theoretically, supersymmetric gravitation is best described by the theory of superstrings.This correlated American and European proposal, is a direct response to the new experimental data that the LHC particle accelerator and the upcoming WMAP, Planck, LSST and JDEM cosmological observations will provide over the next several years and beyond. This proposal seeks to compare the results of cutting-edge theoretical physics, specifically supersymmetry, superstrings and M-theory, with this data. The intent is to provide a theoretical basis for the matter content of nature, the origins of mass, an explanation of dark matter and dark energy, the nature of quantum gravitation and the origin and properties of the hot Big Bang.

大型强子对撞机将寻找新的对称性和物质形式。特别是，LHC将寻找超对称性，该超对称性将颗粒与不同的固有旋转角动量相关联。超对称对于理解粒子物理的重要方面，例如力和暗物质的统一至关重要。它也是超弦理论和量子引力中的基本要素的要求。如果发现超对称性，它将伴随大量的新粒子，称为Superpartners。它们的存在和特性将在LHC上确定。天体物理观察也进入了一个新时代。 WMAP和Planck卫星对宇宙微波背景的成像将提供有关早期宇宙和宇宙结构起源的详细信息。拟议的JDEM和LSST实验将提供有关暗能量和暗物质特性的精确探针。此外，Ligo和Lisa将测量重力波。所有这些天体物理现象从根本上探测了引力理论，而有些人（例如暗物质）可能与超对称性有关。从理论上讲，超对称引力最好通过超级弦理论来描述。这种相关的美国和欧洲提案是对LHC粒子加速器以及即将到来的WMAP，Planck，LSST和JDEM COSMOGOGIOG的新实验数据的直接响应。该提案旨在比较最先进的理论物理学的结果，特别是超对称性，超对称性和M理论的结果。目的是为自然的物质内容，质量的起源，暗物质和暗能量的解释，量子吸引力的性质以及热大爆炸的起源和特性提供理论基础。
