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.

该奖项支持锡耶纳集团作为 CMS 合作的一部分，CMS 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：寻找标准模型之外的新物理学、开放数据以及推广和教育。该小组正在为一项成熟的分析做出贡献，寻找顶夸克（已知最重的基本粒子）的禁衰变，并且最近提议使用 CMS 探测器来寻找来自探测器外部的粒子，可能来自暗物质湮灭。该小组定期为数据保存和开放获取工作做出贡献，主要是帮助组织研讨会，教其他人如何访问和分析这些丰富的数据集。最后，锡耶纳小组有着令人兴奋的外展工作历史，包括为高中建造云室和维护一个网站，允许其他人访问简化的数据和在课堂上使用的计算练习。科学工作将在 3 个方面进行：1)寻找顶夸克的重子数违规衰变。这种搜索涉及从完全强子衰变模式重建顶夸克，然后寻找已衰变成两个喷流和一个带电轻子的伙伴顶夸克，后者违反了重子数和轻子数守恒定律。使用 BaBar 数据集中的数据正在最终确定 B 介子的类似搜索。 2.) 暗物质的间接探测。该小组建议使用 CMS 探测器来寻找从地面向上传播的 μ 子，这些 μ 子是由地球引力束缚的暗物质粒子湮灭产生的。 3）开放数据。该小组将通过组织和促进研讨会以及编写所需的教程文档来教其他人如何分析开放数据集，继续为数据保存和开放获取工作做出贡献。此外，作为 US-CMS MREFC-EPO 工作的联合协调员，PI 将为代表性不足的少数族裔本科生组织年度暑期实习计划，将他们安置在为 CMS 升级做出贡献的机构中。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，同时鼓励锡耶纳的学生也这样做，为当地学校建造由珀尔帖驱动的云室，并将恢复针对高中教师的潜在研讨会计划。将为希望在课堂上引入真实数据的教师提供 Python 教学的数据和资源。该奖项反映了 NSF 的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。
