Exploring Electroweak Symmetry Breaking at the LHC with ATLAS's Fast TracKer

该奖项支持一个项目，该项目是寻找在标准模型(SM)中没有解释的物理学的一部分，标准模型(SM)理论描述了组成宇宙中已知可见物质的基本粒子。这将使用欧洲核子研究中心(CERN)(瑞士的欧洲粒子物理实验室)的大型强子对撞机(LHC)的ATLAS多粒子探测器来完成。2012年，ATLAS和另一台大型探测器在大型强子对撞机上发现了希格斯玻色子(H)。H是SM预测的最后一个存在的粒子。它的发现是大型强子对撞机的目标之一。在这个项目中，PI和她的一小群科学家将使用大型强子对撞机，运行能量是2012年的两倍(13TeV)。他们将寻找a H衰变到b反b夸克对(Bb)的事件。这种衰变的细节，如它们发生的频率，可以揭示是否存在其他在SM的各种扩展中预测的类希格斯粒子。增加的能量还将使他们能够寻找更远、更大质量的类希格斯态。她和她的团队还将在ATLAS探测器本身的升级计划中发挥作用。他们将致力于一种设备的开发和使用，这种设备可以非常快速地重建硅基设备的数据，绘制出带电粒子通过它们的路径。这项提议将支持一名PI、一名博士后研究员和一名研究生。该小组将收集和分析大型强子对撞机第二次运行的事件，该运行从2015年夏天开始，一直持续到2017年底。大型强子对撞机将以13TeV的能量运行，这是迄今为止所有加速器中达到的最高能量。该小组的主要重点将是寻找包括H到BB、BB tau+tau-、W+BB衰变的模式，以及其他更大质量的模式。他们还将继续开发FTK，这是一种可以在赛事中快速重建赛道的硬件设备。该设备将在处理预期的高速率和高密度数据方面发挥关键作用。

This award supports a project that is part of a search for physics that does not have an explanation in the Standard Model (SM), the theory that describes the elementary particles making up the known visible matter in the universe. This will be done using the ATLAS multi-particle detector at the Large Hadron Collider (LHC) at CERN (the European particle physics laboratory in Switzerland). In 2012 the Higgs Boson (H) was discovered at the LHC by both ATLAS and another large detector. The H was the last particle predicted to exist by the SM. Its discovery was one of the goals for the LHC. In this project, the PI and her small group of scientists will use the LHC running at twice the energy (13 TeV) achieved in 2012. They will look for events in which an H decays to a b anti-b quark pair (bb). The details of such decays, such as the frequency with which they occur, can reveal whether or not other Higgs-like particles, predicted in various extensions of the SM, exist. The increased energy will also allow them to search for further, more massive Higgs-like states. She and her 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 very rapidly reconstructs data from silicon-based devices that map out the paths of charged particles passing through them. This proposal will support one PI, a postdoctoral fellow and a graduate student. This group will collect and analyze events from run II of the LHC which begins in the summer of 2015 and continues through the end of 2017. The LHC will be run at 13 TeV, the highest energy yet reached in any accelerator. The group's primary focus will lie in searches for modes that will include decays of H to bb, bb tau+tau-, W+bb and also to other more massive modes. They will also continue their development of the FTK, a hardware device that can quickly reconstruct the tracks in an event. This device will play a crucial role in handling the high rate and density of data anticipated.
