This award funds the research activities of Professors Kaustubh Agashe, Zacharia Chacko, S. James Gates,Jr. Rabindra N. Mohapatra and Raman Sundrum at the University of Maryland. The project deals with understanding the fundamental forces and matter in the universe. Our current understanding of them is based on the standard model, which has been extremely successful in explaining most known natural phenomena. There are however several aspects of the model that indicate that there is a lot of unknown physics beyond it waiting to be unearthed. The existence of masses for a tiny particle called neutrino that fills the universe and the existence of dark matter, the dominant form of matter in the universe, are but two examples which the standard model cannot explain. On a conceptual level, why the recently discovered Higgs boson weighs as much as it does, why is there more matter than antimatter in the universe, and why there are three kinds of building blocks of matter which are very similar, are some other examples that cry out for physics beyond the standard model for their understanding. Using the new funding, the investigators will continue their attempts to solve these problems, using approaches suggested by them and others, and propose ways to test them at the CERN Large Hadron Collider (LHC) as well as planned neutrino experiments at Fermilab. It is hoped that these studies will uncover new forces and new forms of matter which will revolutionize our thinking about the universe and its evolution.The researchers are recognized in the community for having made seminal contributions to some of the major approaches to address the problems mentioned : warped extra dimensions (known as "Randall-Sundrum models"), existence of new boson fermion symmetries (known as supergravity) and ways to break this symmetry (known as "gaugino- and anomaly mediated susy breaking"), twin Higgs theory as a way to understand the Higgs boson mass, grand unification of all forces and matter, left-right symmetry of all forces as a precursor to grand unification and seesaw mechanism for understanding why neutrino masses are so tiny. Together with their postdocs and students they want to continue their activities while at the same time paying attention to any new discoveries from LHC as well as other experiments

该奖项资助教授Kaujuh Agashe，Zacharia Chacko，S。小詹姆斯·盖茨Rabindra N.马里兰州大学的莫哈帕特拉和拉曼桑德拉姆。该项目涉及理解宇宙中的基本力和物质。我们目前对它们的理解是基于标准模型，标准模型在解释大多数已知的自然现象方面非常成功。然而，该模型的几个方面表明，在它之外还有许多未知的物理学有待发掘。充满宇宙的称为中微子的微小粒子的质量的存在，以及宇宙中物质的主要形式暗物质的存在，只是标准模型无法解释的两个例子。在概念层面上，为什么最近发现的希格斯玻色子的重量和它一样大，为什么宇宙中的物质比反物质多，为什么有三种非常相似的物质组成部分，这些都是其他一些例子，这些例子需要物理学超越标准模型来理解。利用新的资金，研究人员将继续尝试解决这些问题，使用他们和其他人建议的方法，并提出在欧洲核子研究中心大型强子对撞机（LHC）以及费米实验室计划的中微子实验中测试它们的方法。希望这些研究能揭示新的力量和新的物质形式，从而彻底改变我们对宇宙及其演化的看法。研究人员在解决上述问题的一些主要方法上作出了开创性的贡献，在社会上得到认可：翘曲额外维（称为“兰德尔-桑德拉姆模型”），新玻色子费米子对称性的存在（被称为超引力）和打破这种对称性的方法（被称为“高吉诺和异常介导的susy打破”），孪生希格斯理论作为理解希格斯玻色子质量的一种方式，所有力和物质的大统一，所有力的左右对称性是大统一和跷跷板机制的先驱，可以理解为什么中微子质量如此之小。与他们的博士后和学生一起，他们希望继续他们的活动，同时关注LHC和其他实验的任何新发现
