This project is devoted to research using ATLAS, a multi-purpose particle physics detector situated around the 27 km ring of the Large Hadron Collider (LHC) located at CERN, the European particle physics laboratory near Geneva, Switzerland. The goal of the project is to explore the fundamental nature of the universe in order to understand its evolution from the hot, dense soup of energy and matter existing soon after the Big Bang to the cool, diffuse universe we see today. The interactions and evolution of the fundamental constituents of the universe are well described by the Standard Model (SM) of Particle Physics that has been very successful in predicting the behavior of nature in the currently available energy regimes. The LHC is expected to restart operations in 2015 after a two-year upgrade program that allows the proton-proton collisions to reach an energy of 13 Tera-electron-Volt, almost twice the highest energy yet produced in any human-made device. This energy regime will allow for further understanding of the SM, exploration of the properties of the newly discovered Higgs Boson and the search for undiscovered particles and phenomena not described by the SM, yet believed to exist. In this research project Professor Moss and his group at California State University, Sacramento (Sacramento State) will probe the electroweak sector of the SM using data collected ATLAS to test the SM at the new energy regime and to search for new phenomena. They propose to study couplings of Higgs Bosons to the electro-weak Z Bosons. Moss and his group, along with their colleagues in ATLAS will perform studies to optimize the performance of the ATLAS Pixel Detector and Diamond Beam Monitor and develop software and user interfaces for the supervisory controls and data acquisition of the ATLAS Detector.

该项目致力于使用ATLAS进行研究，这是一种多用途粒子物理探测器，位于大型强子对撞机(LHC)27公里环周围，位于瑞士日内瓦附近的欧洲粒子物理实验室CERN。该项目的目标是探索宇宙的基本性质，以了解它从大爆炸后不久存在的热而稠密的能量和物质汤到我们今天看到的冷而弥漫的宇宙的演化。粒子物理的标准模型(SM)很好地描述了宇宙基本成分的相互作用和演化，该模型在预测当前可用能量范围内的自然行为方面非常成功。大型强子对撞机预计在两年的升级计划后于2015年重新开始运行，该计划允许质子-质子碰撞的能量达到13万亿电子伏特，几乎是任何人造设备产生的最高能量的两倍。这一能量机制将允许进一步了解SM，探索新发现的希格斯玻色子的性质，以及寻找SM没有描述但被认为存在的未被发现的粒子和现象。在这项研究项目中，莫斯教授和他的加州州立大学(萨克拉门托州立大学)的团队将使用收集的ATLAS数据来探测SM的电弱部分，以测试新能源制度下的SM，并寻找新的现象。他们建议研究希格斯玻色子与电弱Z玻色子的耦合。莫斯和他的团队将与他们在ATLAS的同事一起进行研究，以优化ATLAS像素探测器和钻石波束监测器的性能，并为ATLAS探测器的监督控制和数据采集开发软件和用户界面。
