This award funds the research activities of Professor Nikolaos Kidonakis at Kennesaw State University.This research project will involve calculations for the production of elementary particles such as the top quark, the Higgs boson, and Z bosons at the Large Hadron Collider (LHC), the world's highest-energy collider. The top quark is the most massive fundamental particle that has ever been discovered: it has many unique properties and may be crucial to understanding the origin of electroweak symmetry breaking. For these reasons, the top quark was the centerpiece of the physics program at the Tevatron collider at Fermilab, and it is now a central part of the physics program at the LHC. Similarly, the Higgs boson is the particle thought to be responsible for mass generation and its discovery is also a priority for the LHC. As part of this project, Professor Kidonakis will improve theoretical predictions for top-quark production in top-antitop and single-top channels as well as for Higgs production and other processes. He will do this by performing state-of-the-art calculations of higher-order corrections. These calculations will ultimately be important for understanding the implications of upcoming LHC data.This work is also envisioned to have significant broader impacts. The proposed research is very timely since it addresses physics that is relevant to the LHC. The research findings will also be widely disseminated through publication in refereed journals and presentations in international conferences and workshops. Finally, this project will strengthen the educational and research programs at Kennesaw State University. Professor Kidonakis has actively involved undergraduate and graduate students in his research, and this project offers numerous research and educational opportunities for student involvement.

该奖项资助肯纳索州立大学尼古拉斯·基多纳基斯教授的研究活动。这项研究项目将涉及在世界上能量最高的对撞机大型强子对撞机(LHC)上产生顶夸克、希格斯玻色子和Z玻色子等基本粒子的计算。顶夸克是迄今发现的质量最大的基本粒子：它具有许多独特的性质，对于理解弱电对称破缺的起源可能是至关重要的。由于这些原因，顶夸克是费米实验室Tevatron对撞机物理计划的核心，现在也是LHC物理计划的核心部分。同样，希格斯玻色子被认为是产生质量的粒子，它的发现也是大型强子对撞机的优先事项。作为该项目的一部分，Kidonakis教授将改进顶-反顶和单顶通道中顶-夸克产生以及希格斯产生和其他过程的理论预测。他将通过执行最先进的高阶修正计算来做到这一点。这些计算最终将对理解即将到来的大型强子对撞机数据的含义非常重要。这项工作预计也将产生重大的更广泛的影响。这项拟议的研究非常及时，因为它涉及与大型强子对撞机相关的物理问题。研究成果还将通过在被引用的期刊上发表以及在国际会议和讲习班上发表演讲的方式广泛传播。最后，该项目将加强肯纳索州立大学的教育和研究项目。Kidonakis教授积极地让本科生和研究生参与他的研究，这个项目为学生参与提供了大量的研究和教育机会。
