BTeV Research and Development

该提案要求资金继续研究和发展（R&amp；D）的BTeV实验。这个实验的中心焦点将放在b夸克和c夸克的弱衰变上。非常成功的电弱相互作用标准模型（SM）不能解释不同的夸克或轻子质量或夸克之间的不同耦合。需要进行许多关键的测试和测量，以更好地确定模型的参数，并在数据中寻找与SM的偏差。这些变化可能成为“新物理学”的证据，比如解释早期宇宙中CP的破坏与夸克和中微子的振荡行为之间的联系。BTeV实验将在费米国家加速器实验室的质子与反质子碰撞的Tevatron上进行。这些碰撞产生非常高的b-夸克和c-夸克速率。通过授权大学小组进行仪器研发，这项活动将直接促进研究生和本科生的教育。

This proposal requests funds to continue Research and Development (R&D) for the BTeV experiment. The central focus of this experiment will be on the weak decays of the b-quark and c-quark. The very successful Standard Model (SM) of Electroweak Interactions cannot explain the different quark or lepton masses or the different couplings between the quarks. Many crucial tests and measurements need to be done to better determine the parameters of the model and to search for deviations from the SM in the data. Such variations could be evidence for "New Physics", such as explaining the connections between CP violation in the early universe and the oscillatory behavior of quarks and neutrinos. The BTeV experiment will run at the Fermi National Accelerator Laboratory's Tevatron that collides protons with anti-protons. These collisions produce very high rates of b- and c-quarks. By empowering University groups to conduct instrumentation R&D, this activity will promote directly the education of graduate and undergraduate students.
