项目摘要

Following the discovery of the Higgs boson at the Large Hadron Collider (LHC) at CERN, Geneva, Switzerland, a primary scientific goal of high energy physicists has been to characterize the properties of this new particle. The Higgs itself is a potential portal to new physics, providing connections between the Standard Model of particle physics and new phenomena, such as signatures of possible new forces of nature or evidence of dark matter. Through this CAREER Award, Martinez Outschoorn and her UIUC research team will address such issues both analytically and technically in the ATLAS Experiment. The UIUC group is developing and implementing new analytical tools to search for Higgs bosons decaying into pairs of hypothetical new spin-zero particles, which subsequently decay into known particles such as b-quarks, electrons and muons that can be observed directly in the ATLAS detector. This is tactically challenging, because although the Higgs Mass is large, the masses of the sought for spin-zero particles are low and the energies of the observed particles are similarly low. Additionally, these events are expected to be very rare, and to find them requires high intensity colliding beams at the LHC over several years. To enhance the technical capabilities of the ATLAS detector to observe these particles, the UIUC group is collaborating with ATLAS colleagues in the development of new electronics upgrades to the experiment, to allow for the effective triggering and recording of these particles. Martinez Outschoorn brings significant experience in outreach and education to her companion program called the "Particle Adventure", which will connect elementary and middle school students in grades 4-8, including children from underrepresented and at-risk groups, to the excitement of physics with the aid of undergraduate and graduate student volunteers from the UIUC Physics Department. This creative project brings concepts of particle physics into school classrooms in an interactive way and provides opportunities for young students to interact with physicists at work both locally and at CERN.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.

在瑞士日内瓦欧洲核子研究中心的大型强子对撞机(LHC)上发现希格斯玻色子后，高能物理学家的一个主要科学目标是表征这种新粒子的性质。希格斯粒子本身是通向新物理学的潜在门户，提供了粒子物理标准模型和新现象之间的联系，例如可能存在的新自然力的信号或暗物质的证据。通过这个职业奖，Martinez Outschorn和她的UIUC研究团队将在ATLAS实验中从分析和技术上解决这些问题。UIUC小组正在开发和实施新的分析工具，以搜索希格斯玻色子衰变成一对假想的新的自旋为零的粒子，这些粒子随后衰变成可在ATLAS探测器中直接观测到的已知粒子，如b夸克、电子和µ子。这在战术上具有挑战性，因为尽管希格斯质量很大，但寻找自旋为零的粒子的质量很低，观测到的粒子的能量也同样很低。此外，这些事件预计将非常罕见，而且要找到它们，需要大型强子对撞机在几年内进行高强度碰撞。为了增强ATLAS探测器观测这些颗粒的技术能力，UIUC小组正在与ATLAS的同事合作，为实验开发新的电子升级，以便有效地触发和记录这些颗粒。在UIUC物理系的本科生和研究生志愿者的帮助下，Martinez Outschorn为她的伙伴项目“粒子探险”带来了丰富的推广和教育经验，该项目将把4-8年级的小学生和中学生，包括来自代表性不足和高危群体的儿童，与物理学的兴奋联系起来。这个创造性的项目以互动的方式将粒子物理的概念带入学校课堂，并为年轻学生提供在当地和欧洲核子研究中心与工作中的物理学家互动的机会。该奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。
