Experimental Particle Physics at Hadron Colliders

本提案要求继续支持东北大学伍德小组在实验基本粒子物理方面的研究项目，主要基于费米实验室Tevatron对撞机的D0实验和欧洲核子研究中心大型强子对撞机（LHC）的CMS实验。在过去的几十年里，物理学家已经能够越来越详细地描述构成宇宙的基本粒子以及它们之间的相互作用。这一成功很大程度上要归功于费米实验室的Tevatron项目，D0和CDF做出了重大贡献。这个NEU小组在D0实验的构建和提出的物理问题以及许多领导角色方面做出了重大贡献。伍德目前是D0的联合发言人。该小组正在研究的物理主题对于理解标准模型的电弱部分和标准模型之外的物理非常重要。这些包括W/Z +射流的产生、ZZ的产生、希格斯的搜索和顶夸克的性质。与此同时，大型强子对撞机和ATLAS将开始在新的能量和光度体系中运行，这将为发现和测量带来更大的希望，从而改变我们对世界是如何构建的以及支配世界运行的定律本质的看法。这个小组现在正在过渡到CMS项目，在那里它将发挥其在μ子探测和识别方面的丰富经验，在μ子+射流研究中发挥领导作用——这是一种对各种新物理过程敏感的特征。在更广泛的影响方面，该小组将继续在QuarkNet项目内开展工作。在东北大学强有力的合作教育项目的支持下，该小组将继续定期让本科生参与CERN的实质性和有意义的为期六个月的项目研究。作为D0的联合发言人，Wood将积极与媒体合作，与公众分享希格斯粒子搜索和其他潜在发现的兴奋。该小组计划主持和组织重要会议，Barberis将继续通过她与费米实验室用户执行委员会的合作，向美国国会传达高能研究的价值。

This proposal requests continuing support for a program of research for the Wood group at Northeastern University (NEU) in experimental elementary particle physics based primarily on the D0 experiment at the Fermilab Tevatron collider and the CMS experiment at the Large Hadron Collider (LHC) at CERN.For the past few decades, physicists have been able to describe with increasing detail the fundamental particles that make up the Universe and the interactions between them. Much of this success has been due to the Tevatron program at Fermilab with D0 and CDF making major contributions. This NEU group has made major contributions to the D0 experiment in its construction and in the physics questions proposed as well as in many leadership roles. Wood is presently co-spokesman of D0. The group is pursuing physics topics which are important for understanding the electroweak sector of the Standard Model and physics beyond the Standard Model. These include W/Z + jets production, ZZ production, Higgs searches, and top quark properties. At the same time the LHC and ATLAS will start operation in new regimes of energy and luminosity holding even greater promise for discoveries and measurements leading to revisions of our views on how the world is constructed and the nature of the laws that govern its operation. This group is now transitioning into the CMS program where it will parlay its wealth of experience in muon detection and identification into a leadership role in muon + jets studies - a signature that is sensitive to a variety of new physics processes. On Broader Impacts, the group will continue its work within the QuarkNet program. With the strong cooperative education program at Northeastern University, the group will continue to routinely involve undergraduates in research with substantial and meaningful six-month projects at CERN. In his role and co-spokesperson of D0, Wood will work actively with the press to share with the public the excitement of the Higgs search and other potential discoveries at the Tevatron. The group plans to host and organize important conferences, and Barberis will continue to communicate the value of high energy research to the US Congress through her work with the Fermilab Users Executive Committee.
