项目摘要

This award funds the research activities of Professor Alakabha Datta at the University of Mississippi. High-energy physics focuses on discovering the fundamental building blocks of matter and how they interact with each other. There are two ways in which high-energy physicists try to discover new particles and learn about the laws that govern them. The first approach is to create conditions at high energies where these new states of matter will be produced, and the second approach is to make very precise measurements at lower energies where the indirect effects of these new particles can be detected. Professor Datta's work focuses on the second approach and involves developing methods that can search for new particles and test theories associated with these particles via precision measurements. Over the last few years hints have emerged at several experiments that show deviations from the existing theory. These anomalies could indicate the existence of new fundamental particles and Professor Datta's research will aim to confirm these anomalies and isolate the new particles causing these effects. As a result, research in this area advances the national interest by promoting the progress of science in one of its most fundamental directions: the discovery and understanding of new physical laws. This project is also envisioned to have significant broader impacts. Professor Datta will involve graduate students in his research, and thereby provide critical training for junior physicists beginning research in this field. He also intends to give public lectures on his research results at various schools and universities, including institutions with significant minority-student enrollments. He will also develop new course curricula based on the results of his research. More technically, Professor Datta will explore theories that provide simultaneous explanations of the various flavor anomalies. He will investigate models that contain not only heavy new particles but also light and hidden-sector particles. He will also study how these theories can be tested using various experiments dedicated to neutrino physics, dark-matter searches, and new heavy-particle searches.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该奖项为密西西比大学的Alakabha Datta教授的研究活动提供资金。高能物理学的重点是发现物质的基本组成部分以及它们如何相互作用。高能物理学家有两种方法试图发现新粒子并了解支配它们的定律。第一种方法是在高能量下创造条件，在那里产生这些新的物质状态，第二种方法是在较低能量下进行非常精确的测量，在那里可以检测到这些新粒子的间接影响。达塔教授的工作重点是第二种方法，包括开发可以通过精确测量来寻找新粒子和测试与这些粒子相关的理论的方法。在过去的几年里，已经有迹象表明一些实验偏离了现有的理论。这些异常可能表明存在新的基本粒子，达塔教授的研究将旨在确认这些异常并分离出导致这些效应的新粒子。因此，这一领域的研究通过促进科学在其最基本的方向之一的进步来促进国家利益：发现和理解新的物理定律。预计该项目还将产生更广泛的重大影响。达塔教授将让研究生参与他的研究，从而为在这一领域开始研究的初级物理学家提供关键的培训。他还打算在各种学校和大学，包括少数民族学生人数较多的机构，就其研究成果发表公开演讲。他还将根据他的研究成果开发新的课程。更技术性地，达塔教授将探索理论，提供各种风味异常的同时解释。他将研究不仅包含新的重粒子，而且包含轻粒子和隐藏扇区粒子的模型。他还将研究如何使用各种致力于中微子物理学、暗物质搜索和新的重粒子搜索的实验来验证这些理论。该奖项反映了NSF的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。
