Explorations in High Energy Physics at the Large Hadron Collider with the ATLAS Experiment

该项目致力于使用ATLAS进行研究，ATLAS是一个多用途粒子物理探测器，位于瑞士日内瓦附近的欧洲粒子物理实验室CERN的大型强子对撞机（LHC）27公里环周围。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，密集的能量和物质汤到我们今天看到的凉爽，弥漫的宇宙的演变。 粒子物理学的标准模型（SM）很好地描述了宇宙基本组成部分的相互作用和演化，该模型在预测当前可用能量状态下的自然行为方面非常成功。 经过两年的升级计划，LHC预计将于2015年重新开始运行，该计划允许质子-质子碰撞达到13太电子伏特的能量，几乎是任何人造设备产生的最高能量的两倍。 这种能量机制将允许进一步理解SM，探索新发现的希格斯玻色子的性质，并寻找未被SM描述但被认为存在的未发现的粒子和现象。在这个研究项目中，加州州立大学萨克拉门托分校的Moss教授和他的团队将使用ATLAS收集的数据来探测SM的电弱部分，以在新的能量状态下测试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。 Moss和他的团队沿着ATLAS的同事们将进行研究，以优化ATLAS像素探测器和金刚石光束监视器的性能，并为ATLAS探测器的监控和数据采集开发软件和用户界面。

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.
