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阿拉卡巴·达塔（Alakabha Datta）教授的研究活动提供资金。高能物理学重点是发现物质的基本构建基础以及它们如何相互作用。高能物理学家试图发现新粒子并了解支配它们的法律的方式有两种方法。第一种方法是在将产生这些新物质状态的高能量下创建条件，第二种方法是在可以检测到这些新粒子的间接效果的较低能量的情况下进行非常精确的测量。达塔教授的工作着重于第二种方法，并涉及开发可以通过精确测量来搜索与这些粒子相关的新粒子的方法。在过去的几年中，一些暗示与现有理论偏离的实验中出现了暗示。这些异常可能表明存在新的基本颗粒，而达塔教授的研究将旨在确认这些异常并隔离引起这些效果的新颗粒。结果，该领域的研究通过以最基本的方向之一促进科学进步来提高国家利益：对新物理定律的发现和理解。还设想该项目具有更广泛的影响。 Datta教授将与研究生参与他的研究，从而为初级物理学家开始在该领域的研究。他还打算在各种学校和大学中就其研究成果进行公开讲座，包括大量少数族裔入学的机构。他还将根据他的研究结果开发新课程。从技术上讲，达塔教授将探索理论，这些理论同时解释了各种风味异常。他将研究不仅包含重型新颗粒，而且还包含浅色和隐藏区域颗粒的模型。他还将研究如何使用专门针对中微子物理学，深色 - 物体搜索和新的重粒子搜索的各种实验来测试这些理论。该奖项反映了NSF的法定任务，并被认为是值得通过基金会的智力优点和更广泛的影响审查标准通过评估来进行评估的。
