This RUI award funds the research activities of Professor Bhubanjyoti Bhattacharya at Lawrence Technological University.Although highly successful, the Standard Model (SM) of Particle Physics has several limitations. One such limitation is its inability to resolve our universe's matter-antimatter asymmetry puzzle. The amount of matter in the universe --- surprisingly and unexpectedly –-- far exceeds the amount of antimatter. A fundamental symmetry called Charge-Parity (CP) relates matter with antimatter. As a result, any new physics beyond the SM (so-called "BSM" physics) must therefore have a large amount of CP violation in order to help solve this puzzle. Professor Bhattacharya's scientific research will provide further insight into our understanding of CP violation in BSM theories involving new hypothetical particles. Research in this area advances the national interest by promoting the progress of science in understanding the fundamental properties of nature through the creation of new theoretical frameworks. This project is also envisioned to have significant broader impacts. Undergraduate students at Lawrence Tech, working under the supervision of Professor Bhattacharya, will employ model-independent techniques to compare data with theory, identify deviations in experimental measurements from the SM, and create novel solutions in the form of new-physics models that alleviate tensions within the data. Professor Bhattacharya's students will thus become familiar with cutting-edge computational techniques and contribute to the future American workforce.More technically, Professor Bhattacharya will investigate the decay distributions of heavy mesons (such as B and D mesons) as functions of multiple kinematic variables, using several theoretical tools. He will employ flavor-SU(3) symmetry to investigate hadronic decays and effective-field theory approaches to explore semi-leptonic decays. His research will examine these decays in light of new-physics models with hypothetical particles such as vectorlike fermions, leptoquarks, axionlike particles, and higgslike particles. These projects will create opportunities for delivering a scientific research-based education to undergraduate students while generating increased interest in and greater understanding of particle physics research among the general public.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.

这项RUI奖为劳伦斯技术大学的Bhubanjyoti Bhattacharya教授的研究活动提供了资金。尽管非常成功，但粒子物理学的标准模型（SM）有几个限制。这样的局限性之一就是它无法解决我们宇宙的物质抗对称性难题。宇宙中的物质数量 - 令人惊讶的是 - 远远超过了反物质的量。一个称为电荷 - 偏度（CP）的基本对称性与反物质有关。结果，SM（所谓的“ BSM”物理学）以外的任何新物理学都必须违反大量CP，以帮助解决这一难题。 Bhattacharya教授的科学研究将进一步了解我们对涉及新假设颗粒的BSM理论中CP违规的理解。该领域的研究通过促进科学的进步来促进国家利益，从而通过创建新的理论框架来理解自然的基本特性。还设想该项目具有更广泛的影响。在Bhattacharya教授的监督下工作的Lawrence Tech的本科生将采用与模型无关的技术来比较数据与理论，确定来自SM的实验测量中的出发，并以新的解决方案的形式来减轻数据中的紧张关系。因此，Bhattacharya教授的学生将熟悉尖端的计算技术，并为未来的美国劳动力做出贡献。从技术上讲，Bhattacharya教授将研究重型介子（例如B和D Mesons）作为多个Kinematic变量的功能，使用多种理论工具，将重型膜（例如B和D Mesons）作为多个运动变量的函数。他将采用风味-SU（3）对称性来研究野蛮的衰变和有效场理论方法来探索半静态衰变。他的研究将根据具有假设的颗粒（例如矢量般的费米子，leptoquarks，axionlike颗粒和希格斯般的颗粒）进行假设颗粒的新生理学模型检查这些衰变。这些项目将为本科生提供基于科学的研究教育的机会，同时对公众对粒子物理研究的浓厚兴趣和对粒子物理研究的更多了解。该奖项反映了NSF的法定任务，并通过使用基金会的知识分子优点和更广泛的影响审查标准通过评估来诚实地支持支持。
