This award supports the Siena group as part of the CMS collaboration, one of the four general-purpose detectors at the Large Hadron Collider, the largest particle accelerator in the world. The work, largely done by undergraduate students, will be on three fronts: searches for new physics beyond the Standard Model, open data, and outreach and education. The group is contributing to a mature analysis searching for forbidden decays of the top quark, the heaviest known elementary particles, and has recently proposed using the CMS detector to look for particles coming from outside of the detector, possibly from dark matter annihilations. The group makes regular contributions to the data preservation and open access efforts, primarily by helping organize workshops to teach others how to access and analyze these rich datasets. Lastly, the Siena group has a history of exciting outreach efforts including building cloud chambers for high schools and maintaining a website that allows others to access simplified data and computational exercises for use in the classroom.The scientific work will be on 3 fronts: 1) the search for Baryon-number violating decays of the top quark. This search involves reconstructing a top-quark from the fully hadronic decay mode and then looking for a partner top-quark which has decayed to two jets and a charged lepton, the latter of which violates both baryon- and lepton-number conservation. A similar search with B mesons is being finalized using data from the BaBar dataset. 2.) An indirect detection of Dark matter. This group proposes using the CMS detector to search for muons traveling up from the ground and produced by the annihilation of dark matter particles that are gravitationally bound in the Earth. 3) Open data. The group will continue to contribute to data preservation and open access efforts by organizing and facilitating workshops and writing the required tutorial documents to teach others how to analyze the open datasets. Furthermore, in his role as co-coordinator of the US-CMS MREFC-EPO effort the PI will organize an annual summer internship program for underrepresented minority undergrads, placing them with institutions contributing to the CMS upgrade. Building on the past education and public outreach effort the PI will continue this work while encouraging Siena students to do the same by building Peltier-powered cloud chambers for local schools and will revive a latent workshop program for high school teachers. Data and resources for python instruction will be provided for teachers who want to introduce real data in the classroom.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该奖项支持Siena集团作为CMS合作的一部分，这是世界上最大的粒子加速器大型强子对撞机的四个通用探测器之一。这项工作主要由本科生完成，将在三个方面进行：搜索超越标准模型，开放数据以及外展和教育的新物理。该组有助于成熟的分析，以寻找最重的已知基本粒子的最重的夸克的禁止腐烂，并且最近提出使用CMS检测器来寻找来自检测器外部的粒子，可能是来自暗物质nih灭的粒子。该小组定期为数据保存和开放访问工作做出贡献，主要是通过帮助组织研讨会来教别人如何访问和分析这些富裕数据集。最后，锡耶纳集团（Siena Group）拥有令人兴奋的外展活动的历史，包括为高中建造云室，并维护一个允许其他人访问简化的数据和计算练习，以便在课堂上使用。科学工作将在3个方面：1）搜索违反顶级夸克腐烂的baryon-number。这项搜索涉及从完全强化的衰减模式重建一个Quark，然后寻找伴侣的Top-Quark，该伴侣已经腐烂到了两个喷气机和一个被带电的Lepton，后者违反了Baryon-和Lepton-number的保护。使用Babar数据集中的数据，正在最终确定与B介子的类似搜索。 2.）间接检测暗物质。该小组建议使用CMS检测器搜索从地面上移动的muons，并通过在地球上重力结合的暗物质颗粒的an灭产生。 3）打开数据。该小组将通过组织和促进研讨会并撰写所需的教程文档来教别人如何分析开放数据集，从而为数据保存和开放访问工作做出贡献。此外，在他担任US-CMS MREFC-EPO努力的协调员中，PI将组织一项年度暑期实习计划，为代表性不足的少数族裔本科生组织，并将其与CMS升级的机构相提并论。在过去的教育和公共宣传工作的基础上，PI将继续这项工作，同时鼓励锡耶纳学生通过为当地学校建造Peltier驱动的云室，并为高中老师提供潜在的研讨会计划。将为想要在课堂上引入真实数据的教师提供有关Python教学的数据和资源。该奖项反映了NSF的法定任务，并且使用基金会的知识分子优点和更广泛的影响审查标准，被认为值得通过评估来提供支持。
