This award supports a new program of research by the MIT group of Mike Williams on the LHCb Experiment at the CERN Large Hadron Collider, Geneva, Switzerland. The primary function of LHCb is to search for physics beyond the Standard Model (BSM) by studying rare and CP-violating decays of b and c hadrons. For at least the next five years, LHCb will be the premier flavor-physics experiment in the world. Williams has been one of the principal architects of the high-level trigger (HLT) for LHCb in the recent past. This trigger allowed LHCb to collect a nearly 100% pure b-bbar sample during experimental operations in 2011 and 2012. The PI wrote this trigger, making MIT uniquely qualified as a group to prepare the experiment to handle future running conditions, including a collision energy of 13-TeV and significantly higher luminosity. MIT has a strong record in outreach, and PI Williams will build upon this tradition with links to the LHCb program. Over the past 6 summers, undergraduate students from the NSF-supported REU program at Hampton University have participated in the MIT Summer Research Program (MSRP). These students are supervised by members of the MIT Laboratory for Nuclear Science (LNS) and interact with various LNS faculty, staff and students. This program provides a unique opportunity for minority students to experience life at a large research institute. Beginning in the summer of 2013, students from this program will be able to do flavor-physics research using LHCb data.

该奖项支持麻省理工学院迈克·威廉姆斯团队在瑞士日内瓦欧洲核子研究中心大型强子对撞机上开展的大型强子对撞机实验的新研究计划。 LHCb 的主要功能是通过研究 b 和 c 强子的罕见衰变和 CP 破坏衰变来寻找标准模型 (BSM) 之外的物理现象。 至少在未来五年内，大型强子对撞机将成为世界上首屈一指的风味物理实验。 威廉姆斯最近一直是 LHCb 高级触发器（HLT）的主要架构师之一。 这个触发器使 LHCb 在 2011 年和 2012 年的实验操作期间收集了近 100% 纯的 b-bbar 样本。PI 编写了这个触发器，使 MIT 成为唯一有资格作为一个小组来准备实验以处理未来的运行条件，包括碰撞能量13-TeV 和显着更高的光度。麻省理工学院在外展方面有着良好的记录，PI Williams 将在这一传统的基础上与 LHCb 项目建立联系。在过去的 6 个暑假里，汉普顿大学 NSF 支持的 REU 项目的本科生参加了麻省理工学院暑期研究项目 (MSRP)。这些学生受到麻省理工学院核科学实验室 (LNS) 成员的监督，并与 LNS 的教职员工和学生互动。该项目为少数族裔学生提供了体验大型研究机构生活的独特机会。从 2013 年夏天开始，该项目的学生将能够使用 LHCb 数据进行风味物理研究。
