This award provides continued support for the experimental particle physics program at SUNY-Stony Brook. The intellectual merit will be new understanding of underlying causes for the breaking of the symmetry in the fundamental forces of nature and searches for physics not described by the Standard Model. This will be done in two experimental programs. The major effort will be with the ATLAS experiment at the Large Hadron Collider (LHC) at CERN in Geneva, Switzerland, where the group will continue support for the calorimeters with an emphasis on measuring electrons, photons, missing energy and long lived-particles that enable studies of W/Z bosons in association with heavy quarks. Active participation in the early physics will include measurement of W boson properties, measuring production of W bosons with jets, and new particle searches. Participating in the DØ experiment at the Fermilab Tevatron the program will extend the search for the Higgs boson, allowing its exclusion if it does not exist within the expected range 115-158 GeV, or finding evidence for its existence if it does. In addition, the group will extend its study of the like-sign dimuon asymmetry, where current results suggest an unexpected CP-violation in the B-sub(s) system and a possible explanation of the matter-antimatter asymmetry in the universe. The broader impact includes 1) development of improved training for high school teachers, 2) continued support for the Mariachi Project that installs detectors to sense high energy cosmic rays in high school classrooms across the region, 3) public outreach through talks on physics research, accelerators and technological spinoffs, and 4) emphasizing in the training of students and postdoctoral scientists the learning of new techniques and effective communication, thereby enabling them to take leadership positions in science and technology industry or government.

该奖项为纽约州立大学石溪分校的实验粒子物理项目提供了持续的支持，其智力价值将是对自然基本力对称性破缺的根本原因的新理解，以及对标准模型未描述的物理学的探索。这将通过两个实验项目完成，其中主要工作是在瑞士日内瓦欧洲核子研究中心大型强子对撞机 (LHC) 上进行的 ATLAS 实验，该小组将继续支持热量计，重点是测量电子和光子。 ， 丢失的能量和长寿命粒子，使 W/Z 玻色子与重夸克相关的研究成为可能费米实验室 Tevatron 的 DØ 实验该计划将扩大对希格斯玻色子的搜索范围，如果希格斯玻色子不存在于 115-158 GeV 的预期范围内，则允许将其排除，或者寻找其存在的证据此外，该小组将扩展其对同号二介子不对称性的研究，目前的结果表明 B-sub 系统中出现了意想不到的 CP 破坏，并可能解释了 B-sub 系统中的物质-反物质不对称性。更广泛的影响包括 1) 改进高中教师培训，2) 继续支持 Mariachi 项目，该项目在整个地区的高中教室安装检测高能宇宙射线的探测器，3) 公众宣传。通过有关物理研究、加速器和技术衍生品的讲座，以及4）在学生和博士后科学家的培训中强调新技术的学习和有效的沟通，从而使他们能够在科技行业或政府中占据领导地位。
