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 Kaustubh Agash、Zacharia Chacko、S. James Gates,Jr. 教授的研究活动。马里兰大学的 Rabindra N. Mohapatra 和 Raman Sundrum。该项目涉及了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，该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，除此之外还有许多未知的物理现象等待被发现。充满宇宙的中微子微小粒子的质量的存在和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如此之大，为什么宇宙中的物质比反物质更多，以及为什么存在三种非常相似的物质构建块，这些都是其他一些例子迫切需要超越标准模型的物理学来理解他们。利用新的资金，研究人员将继续尝试解决这些问题，采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) 以及计划在费米实验室进行的中微子实验进行测试的方法。希望这些研究能够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思考。研究人员因对解决上述问题的一些主要方法做出了开创性贡献而受到社区的认可：扭曲的额外维度（称为“Randall-Sundrum 模型”）、新玻色子费米子对称性（称为超引力）的存在以及打破这种对称性的方法（称为“高吉诺和异常介导的苏西”）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作为大统一的先驱，以及理解为什么中微子质量如此之小的跷跷板机制。他们希望与博士后和学生一起继续他们的活动，同时关注大型强子对撞机以及其他实验的任何新发现
