Abstract0354401 PI: MohapatraThe goal of the research being undertaken by the Maryland Particle TheoryGroup is to search for the ultimate laws that govern the nature of particles, forces and the Universe. The focus will be to explore the nature of physics beyond the successful standard model of strong, weak and electromagnetic forces using results from neutrino physics and theoretical ideas such as supersymmetry, grand unification and string theory. Neutrino masses have already provided some clues as to the nature of this new physics. The current and planned experiments at various laboratories around the world using neutrinos, protons, electrons and muons are expected to add considerably to this knowledge. The plan is to use these results and predict new ones to test the different theoretical ideas mentioned above. This research will also explore ways to resolve some of the puzzles of cosmology such as nature of dark matter in the universe, origin of matter-anti-matter asymmetry, nature of the expansion of the early universe etc. using the same theoretical ideas and propose ways to test them in different experiments.The hope is that this research will provide answers to some of the outstanding questions of modern physics such as (i) what is the origin of the mass of fundamental particles; (ii) are all the diverse forces of nature such as gravity, electro-magnetism, weak and nuclear forces really different manifestations of one force that operates at very short distances; (iii) why are some forces weaker than others; (iv) are the most elementary building blocks of matter point-like particles or strings; (v) are there extra hidden space dimensions in nature? There will be strong participation in this research by post-doctoral associates, graduate students as well as undergraduate and high school students. It will therefore provide training for future scientists by bringing them into close contact with the frontier areas of research in this exciting field.

摘要0354401 PI：马里兰州粒子理论组进行的研究目标是寻找控制颗粒，力和宇宙的本质的最终定律。重点是使用中微子物理学和理论思想（例如超对称性，大统一和弦理论）的结果，超出强大，弱和电磁力的成功标准模型以外的物理性质。中微子群众已经为这种新物理学的性质提供了一些线索。期望使用中微子，质子，电子和MUON的当前和计划的实验在世界各地的各个实验室进行，预计将大大增加这一知识。该计划是使用这些结果并预测新结果来测试上述不同的理论思想。这项研究还将探索解决一些宇宙学难题的方法，例如宇宙中的暗物质本质，物质 - 抗抗物的不对称性，早期宇宙的扩展性质等的性质等的性质等，并提出了相同的理论思想，并提出了在不同的实验中测试它们的方法。希望这项研究能够为现代物理学的质疑提供一些良好的问题的答案，例如现代物理学的质量，诸如INSISIC的质量（诸如INIMES）的（我是I）的（我）属于（我）的（我）; （ii）都是自然的各种力量，例如重力，电磁性，弱和核力量，确实在很短的距离内确实不同； （iii）为什么有些力量比其他力弱； （iv）是物质点状粒子或字符串的最基本的构件； （v）自然界中是否有额外的隐藏空间尺寸？博士后员工，研究生以及本科生和高中生将有很大的参与。因此，它将通过使他们与这个令人兴奋的领域的研究领域保持联系，为未来的科学家提供培训。
