This award funds the research activities of Professor Giovanni Ossola at the New York City College of Technology (City University of New York).The Large Hadron Collider (LHC) at CERN, the largest and most powerful particle collider ever built, has begun operations. A major objective of the LHC is to search for the last missing particle predicted in the Standard Model of fundamental interactions, namely the Higgs boson. However, the process of discovering new particles and interactions requires extraordinary efforts from both the experimental and the theoretical sides of the high-energy physics community in processing, analyzing, and then comparing a huge amount of data with theoretical models and predictions. The main objective of Professor Ossola's research is the development of new theoretical tools in order to increase the precision of these theoretical predictions. Specifically, his research seeks to develop new methods for the automated computation of multi-particle one-loop scattering amplitudes. This project is also envisioned to have significant broader impacts. Professor Ossola aims to establish and maintain a stronger connection between the events taking place at CERN and the New York City College of Technology (CUNY), one of the most diverse institutions of higher education in the United States. This connection will be achieved through presentations within the Physics Departments of the City University of New York, where the ongoing progress at the LHC will be discussed; through the organization of public presentations, which will be directed to a broader audience outside of the physics community; and through the involvement of undergraduate students in activities that will convey the excitement of the new discoveries of science. New ideas and computational techniques will also be integrated into the development of new courses and curricula, which will provide encourage interest and participation in the sciences and technologies.

该奖项资助纽约城市理工学院（纽约城市大学）Giovanni Ossola教授的研究活动。欧洲核子研究中心的大型强子对撞机（LHC）已经开始运行，这是迄今为止建造的最大、最强大的粒子对撞机。大型强子对撞机的一个主要目标是寻找基本相互作用标准模型中预测的最后一种缺失粒子，即希格斯玻色子。然而，发现新粒子和相互作用的过程需要高能物理界的实验和理论方面的非凡努力，在处理，分析，然后将大量数据与理论模型和预测进行比较。Ossola教授研究的主要目标是开发新的理论工具，以提高这些理论预测的精度。具体来说，他的研究旨在开发多粒子单环散射振幅自动计算的新方法。预计该项目还将产生更广泛的重大影响。Ossola教授的目标是在CERN和纽约城市理工学院（CUNY）之间建立和保持更强的联系，纽约城市理工学院是美国最多样化的高等教育机构之一。这种联系将通过在纽约城市大学物理系的演讲来实现，在那里，LHC的持续进展将被讨论；通过组织面向物理界以外更广泛受众的公开演讲；并通过本科生参与的活动，将传达科学的新发现的兴奋。新思想和计算技术也将纳入新课程和课程的发展，这将鼓励人们对科学和技术的兴趣和参与。
