The goal of the theory group involved in this proposal is to understand how the world works at the smallest distances. The group seeks to understand the nature of the space we live in, of the matter and energy that move through it, of the vacuum that fills it, of its history since the beginning of the universe and its fate in the far future, and of the dimensions that might lurk outside it. Soon the Large Hadron Collider (LHC) at CERN in Geneva will begin operating and looking for various new particles predicted by generalization of the standard model of particle physics. The group seeks to deepen our understanding of the new physics we may begin to see at the LHC. The questions that will be addressed in the group's research include the following:. Can we see "unparticles" at the LHC? Research by this group has suggested that the LHC could produce an exotic state of matter that cannot be described in terms ofparticles with definite mass hence "unparticles." This is provides a new example of avery unconventional phenomenon that might appear at the LHC.. Can we use topology to understand Black Holes? The group has recently shown that purely topological aspects of string theory can capture highly non-trivialquantum gravitational corrections to the black hole entropy. The implications of this to better understanding entropy and holography will be pursued in the future research program.. Can we find the Minimal Supersymmetric Standard Model in String theory? The group will pursue new directions that may lead to a very natural embedding of the MSSM in string theory. The broader implications of this research is the hope of better understanding the fundamental nature of space and time at the shortest and largest distances. The group is active in broadening participation of underrepresented groups which include both women and African Americans in cutting-edge research

参与这一提议的理论小组的目标是了解世界是如何在最小距离下运行的。该组织试图了解我们生活的空间的本质，通过它运动的物质和能量，填充它的真空，它自宇宙开始以来的历史和它在遥远未来的命运，以及可能潜藏在它之外的维度。不久，位于日内瓦的欧洲核子研究中心（CERN）的大型强子对撞机（LHC）将开始运行，并寻找由粒子物理学标准模型的推广所预测的各种新粒子。该小组试图加深我们对可能在大型强子对撞机上看到的新物理学的理解。在小组的研究中将涉及的问题包括：。我们能在大型强子对撞机上看到“非粒子”吗？这个小组的研究表明，大型强子对撞机可以产生一种奇异的物质状态，这种状态无法用具有确定质量的粒子来描述，因此被称为“非粒子”。这为大型强子对撞机可能出现的非常规现象提供了一个新的例子。我们能用拓扑学来理解黑洞吗？该小组最近表明，弦理论的纯拓扑方面可以捕捉到黑洞熵的高度非平凡的量子引力修正。这对更好地理解熵和全息术的影响将在未来的研究计划中进行。我们能在弦理论中找到最小超对称标准模型吗？该小组将寻求新的方向，可能导致将MSSM非常自然地嵌入到弦理论中。这项研究的更广泛的意义是希望在最短和最大的距离上更好地理解空间和时间的基本性质。该组织积极扩大代表性不足的群体的参与，包括妇女和非洲裔美国人参与尖端研究
