Experimental Studies of Fundamental Symmetries

纽约州立大学石溪分校的高能物理小组正在研究自然界基本力对称性破缺的根本原因。在两个实验项目中探索了这些问题：费米实验室Tevatron的成熟D 0实验将使其目前的数据积累增加四倍以上，允许对相对较轻的希格斯玻色子进行灵敏的探索，并对可能揭示偏离标准模型的已知粒子进行精确的研究;以及欧洲核子研究中心大型强子对撞机（CERN LHC）的ATLAS实验，该实验将于2007年开始运行，应该会发现标准模型希格斯玻色子并观察新物理的表现。拟议的研究还将支持在政府指导下开发国际直线对撞机计划的努力，国际社会的监督，以及为ILC实验开发探测器仪器。 最后，拟议中的计划将有助于发展MARIACHI实验，该实验将在长岛的高中放置粒子探测器，以探测由高能宇宙射线引起的广泛的空气簇射，以及集中探测从大气层中的宇宙射线电离轨迹反弹的无线电信号。该计划将把前沿科学和计算网格带到高中，激发学生对科学和技术职业的兴趣。

The High Energy Physics Group at the State University of New York atStony Brook is conducting research on the underlying causes for the breaking of the symmetry in the fundamental forces of nature. These are explored in two experimental programs: the mature D0 experiment at the Fermilab Tevatron will more than quadruple its current data accumulation, allowing sensitive exploration of relatively light Higgs bosons and precision studies of known particles that could reveal departures from the Standard Model; and the ATLAS experiment at the CERN LHC which will begin operation in 2007, and should uncover the Standard Model Higgs boson and observe manifestations of the new physics. The proposed research will also support efforts to develop the International Linear Collider program with guidance to the government, oversight in the international community, and development of detector instrumentation for ILC experiments. Lastly, the proposed program will help develop the MARIACHI experiment that would place particle detectors in high schools across Long Island to detect extensive air showers induced by ultrahigh energy cosmic rays, together with centralized detection of radio signals bounced off the cosmic ray ionization trails high in the atmosphere. This program will bring frontline science and computing grids to the high schools, stimulating student interest in science and technology careers.
