In the Standard Model as well as in its Supersymmetric extension, the mechanism proposed to explain electroweak symmetry breaking presents signature particle(s), the Higgs boson(s). This program will cover searches for the Higgs boson(s) at both the Tevatron Collider at Fermilab and the Large Hadron Collider (LHC) at CERN. In particular, the search will be focused on a Higgs decaying into a pair of tau-leptons. The tau -channels offer a clean signature with reduced backgrounds, and are central to the search for all types of Higgs particles such as those deriving from Standard Model, light neutral Supersymmetric, heavy neutral Supersymmetric, charged Supersymmetric theories. Transfer of the expertise from the Tevatron to the LHC will be critical for the success of the Higgs research program of the CMS experiment at the LHC. This proposal will help start a tau -lepton effort within the US part of the CMS Collaboration. Discovering the mechanism responsible for electroweak symmetry breaking and the origin of mass constitutes one of the most important open questions and highest priorities in particle physics today. Fermilab Tevatron and the CERN LHC hadron colliders offer unique discovery opportunities in that front. The PI's research in the last several years has been focused on the quest for the Higgs boson; the signature particle for the prevailing mechanism proposed to explain electroweak symmetry breaking and therefore, brings extensive expertise to the program. The educational and outreach goals are to engage non-traditional participants, namely female high school teachers and students in particle physics research at the scientific frontier, in the hope to infuse these very young women with a love for physics and science in general. The program will build on the strength of the existing QuarkNet project at the University of Notre Dame, but will extend the project in two new directions: putting the emphasis on young women in science; and extending the participation of high school students and teachers from building hardware to physics analysis of Tevatron data aimed at the discovery of the Higgs boson.

在标准模型及其超对称扩展中，用来解释电弱对称性破缺的机制提出了一个签名粒子，希格斯玻色子。该计划将包括在费米实验室的Tevatron对撞机和欧洲核子研究中心的大型强子对撞机（LHC）上寻找希格斯玻色子。特别是，搜索将集中在希格斯衰变为一对τ轻子。tau通道提供了具有减少的背景的干净签名，并且是寻找所有类型的希格斯粒子的中心，例如来自标准模型、轻中性超对称、重中性超对称、带电超对称理论的希格斯粒子。将Tevatron的专业知识转移到LHC对于LHC CMS实验的希格斯研究计划的成功至关重要。这项提议将有助于在CMS合作的美国部分开始一项τ轻子的努力。发现电弱对称性破缺和质量起源的机制是当今粒子物理学中最重要的开放问题之一。费米实验室的Tevatron和欧洲核子研究中心的LHC强子对撞机在这方面提供了独特的发现机会。PI在过去几年的研究一直集中在希格斯玻色子的探索上;希格斯玻色子是解释电弱对称性破缺的流行机制的签名粒子，因此为该计划带来了广泛的专业知识。教育和外联目标是让非传统参与者，即高中女教师和女学生参与科学前沿的粒子物理研究，希望让这些非常年轻的妇女对物理和科学产生普遍的热爱。该计划将以圣母大学现有的QuarkNet项目为基础，但将在两个新的方向上扩展该项目：将重点放在科学领域的年轻女性上;并将高中学生和教师的参与从硬件建设扩展到旨在发现希格斯玻色子的Tevatron数据的物理分析。
