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

该奖项为教授Kaustubh Agashe，Zacharia Chacko，S。JamesGates，Jr的研究活动提供资金。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量和物质。我们目前对它们的理解是基于标准模型，该模型在解释最著名的自然现象方面非常成功。但是，模型的几个方面表明，除了出土之外，还有许多未知物理。一个称为中微子的微小粒子的质量的存在，它充满了宇宙和暗物质的存在，即宇宙中物质的主要形式，只是标准模型无法解释的两个例子。从概念上讲，为什么最近发现的希格斯玻色子的重量与宇宙中的比物质相比，为什么要比反物质更多的东西，以及为什么有三种非常相似的物质构建块，这些示例是其他一些示例，这些示例哭了出来，这些示例超出了标准模型以外的理解。使用新的资金，调查人员将使用他们和其他人建议的方法继续尝试解决这些问题，并提出在CERN大型强子对撞机（LHC）上测试他们的方法，并在费米拉布（Fermilab）进行了计划中的中微子实验。 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 “仪表和异常介导的苏西破裂”），双希格斯理论是一种理解希格斯玻色子质量的一种方式，所有力量和物质的宏伟统一，所有力量的左右对称性作为大统一的先驱和扫索机制，以理解为什么中源群众如此微小。他们希望与他们的博士后学生和学生一起继续活动，同时关注LHC的任何新发现以及其他实验
