This award funds the research activities of Professor Doreen Wackeroth at the University at Buffalo, The State University of New York.Particle physics research has entered an exciting era: The CERN Large Hadron Collider (LHC) is successfully colliding proton beams at energies that allow for the exploration of matter and the laws of physics that govern its properties at the most fundamental level. Despite the enormous success of the Standard Model (SM) in describing all experimentally observed electromagnetic, weak, and strong interactions of the constituents of matter, it is generally accepted that the SM is merely a low-energy approximation to a more fundamental theory which is expected to reveal itself at the LHC in form of the emergence of new, non-SM particles and interactions. Moreover, there is still one prediction of the SM that awaits experimental confirmation: the existence of a Higgs particle, which is thought to be associated with the observed phenonenon of electroweak symmetry breaking. If the SM Higgs boson exists, it will not escape detection at the LHC. However, in order to extract meaningful information from LHC data, the theoretical predictions for relevant LHC processes must be of a precision that exceeds anticipated experimental precision. This project will therefore consist of improving the current predictions for such processes. Specifically, the PI will perform calculations of cross sections at higher orders in perturbation theory and implement these improved calculations in Monte Carlo programs.This project is also envisioned to have significant broader impacts. The proposed calculations are challenging and will provide the graduate students involved with an advanced research experience and with skills valuable beyond the scope of particle-physics research. These research activities will be pursued in collaboration with scientists worldwide, and will further US-international joint scientific efforts. The PI will also continue to organize activities involving the Physics Department's Physics & Arts Exhibition, which aims to convey the excitement of fundamental research to K-12 and undergraduate students as well as to the general public.

该奖项资助了纽约州立大学布法罗分校Doreen Wackeroth教授的研究活动。粒子物理学研究已经进入了一个令人兴奋的时代：欧洲核子研究中心的大型强子对撞机（LHC）成功地碰撞了质子束，其能量允许探索物质和最基本的物理定律。尽管标准模型（SM）在描述所有实验观察到的物质组分的电磁、弱和强相互作用方面取得了巨大的成功，但人们普遍认为，SM只是一个更基本理论的低能近似，预计将在LHC中以新的非SM粒子和相互作用的形式出现。 此外，SM还有一个预测有待实验证实：希格斯粒子的存在，它被认为与观察到的电弱对称性破缺现象有关。 如果SM希格斯玻色子存在，它将不会逃脱LHC的检测。 然而，为了从LHC数据中提取有意义的信息，相关LHC过程的理论预测必须具有超过预期实验精度的精度。 因此，该项目将包括改进目前对这些过程的预测。 具体而言，PI将在微扰理论中进行高阶截面的计算，并在Monte Carlo程序中实现这些改进的计算。该项目也被认为具有重大的广泛影响。所提出的计算是具有挑战性的，并将提供先进的研究经验，并与超出粒子物理学研究范围的宝贵技能参与的研究生。这些研究活动将与世界各地的科学家合作进行，并将进一步推动美国与国际的联合科学努力。PI还将继续举办包括物理系物理艺术展在内的活动，旨在向K-12和本科生以及公众传达基础研究的兴奋。
