The objective of this project is to search for physics that does not have an explanation in the Standard Model (SM), the theory that classifies all the known elementary particles. Using the Large Hadron Collider (LHC) at CERN (the particle European laboratory in Switzerland) this group of scientists will look for events in the ATLAS multi-particle detector where a Z or W Boson (identified by observing electrons or muons to which it decays) is observed moving away from the proton-proton interaction point in the LHC, accompanied by an object that leaves no visible tracks in the detector. This final state can probe many fundamental mysteries of the Universe, e.g. the nature of dark matter, the existence of extra dimensions, and the existence of an extended family of Higgs Bosons predicted by some theories beyond the SM. This group will also play a role in the planned upgrade of the ATLAS detector itself. They will work on the development and use of a device that uses silicon detectors to map out the paths of charged particles passing through. This award will support one PI, a postdoctoral fellow and a graduate student. The PI will continue as a mentor in the U. Washington QuarkNet program, and will also work with high school students from local Seattle High Schools in the MasterClass program. He will also continue to organize events that bring results from the LHC closer to the public.The group will focus on W/Z + large EtransT events in which the particle recoiling against the Boson is invisible and has large, missing transverse energy. Such events would signal the existence of massive neutral particles that could have a number of origins in a variety of theories that lie beyond the SM. The group will also work on data acquisition for use with the ATLAS inner tracker.

该项目的目标是寻找在标准模型（SM）中没有解释的物理学，该理论将所有已知的基本粒子分类。使用欧洲核子研究中心（位于瑞士的粒子欧洲实验室）的大型强子对撞机（LHC），这组科学家将在ATLAS多粒子探测器中寻找事件，其中观察到Z或W玻色子（通过观察它衰变的电子或μ子来识别）远离LHC中的质子-质子相互作用点，伴随着一个在探测器中没有留下可见轨道的物体。这种最终状态可以探索宇宙的许多基本奥秘，例如暗物质的性质，额外维度的存在，以及一些超越SM的理论预测的希格斯玻色子大家族的存在。该小组还将在ATLAS探测器本身的计划升级中发挥作用。他们将致力于开发和使用一种设备，该设备使用硅探测器来绘制带电粒子通过的路径。该奖项将支持一名PI，一名博士后和一名研究生。PI将继续在美国担任导师。华盛顿QuarkNet计划，并将与当地西雅图高中的高中生在大师班计划。他还将继续组织活动，使LHC的结果更接近公众。该小组将专注于W/Z +大EtransT事件，其中粒子反冲玻色子是不可见的，并具有大的，失踪的横向能量。这样的事件将标志着大质量中性粒子的存在，这些粒子可能在SM之外的各种理论中有许多起源。该小组还将致力于与ATLAS内部跟踪器一起使用的数据采集。
