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.

该项目的目的是搜索在标准模型（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。 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.这个最终的状态可以探讨宇宙的许多基本奥秘，例如暗物质的本质，额外的维度的存在以及一个大型的希格斯玻色子家族的存在，这是SM之外的某些理论所预测的。该小组还将在计划的Atlas探测器本身的升级中发挥作用。他们将开发和使用使用硅检测器来绘制经过的带电颗粒的路径的设备。该奖项将支持一个PI，博士后研究员和一名研究生。 PI将继续担任美国华盛顿Quarknet计划的导师，还将与大师班计划的当地西雅图高中的高中学生合作。他还将继续组织活动，使LHC更接近公众。该小组将重点放在W/Z +大型Etranst事件上，在这些事件中，在这些事件中，对玻色子的粒子后退是看不见的，并且具有较大的，缺失的横向能量。这样的事件将表明存在大量中性颗粒，这些颗粒可能具有多种起源，这些理论超出了SM。该小组还将致力于与Atlas Inner Tracker一起使用的数据采集。
