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计划提供了持续的支持。学术价值将是对自然基本力对称性破坏的根本原因的新理解，以及对标准模型没有描述的物理学的探索。这将在两个实验项目中完成。主要工作将是在瑞士日内瓦欧洲核子研究中心的大型强子对撞机（LHC）上进行的ATLAS实验，该小组将继续支持量热计，重点是测量电子，光子，丢失的能量和长寿命粒子，从而能够研究与重夸克相关的W/Z玻色子。在早期物理学的积极参与将包括测量W玻色子的属性，测量生产的W玻色子与喷流，和新的粒子搜索。参与费米实验室Tevatron的Duplex实验，该计划将扩大对希格斯玻色子的搜索，如果它不存在于预期的115-158 GeV范围内，则允许排除它，或者如果它存在，则找到它存在的证据。此外，该小组将扩展其对类似符号的双μ子不对称性的研究，目前的结果表明B-sub（s）系统中存在意想不到的CP违反，并可能解释宇宙中的物质-反物质不对称性。更广泛的影响包括：1）为高中教师提供更好的培训，2）继续支持Mariachi项目，该项目在整个地区的高中教室安装探测器以感知高能宇宙射线，3）通过物理研究，加速器和技术副产品的会谈进行公众宣传，四是在培养学生和博士后时，注重新技术的学习和有效的交流，使他们能够在科技产业或政府中担任领导职务。
