Exploring quantum information with Higgs Bosons and Top Quarks

这项研究的主要目标是在量子比特(顶对)和量子三重(希格斯玻色子)系统中测试贝尔不等式和其他关于量子信息在前所未有的高能下的预测。这样的量子信息研究以前从未在强子对撞机上被探索过，也从未在任何地方以这样的能量被探索过。此外，该项目的希格斯部分将涉及分离H-&GT；WW-&&GT；轻子+喷注的终态，这是一种尚未测试和观测到的希格斯衰变模式。学生将使用ATLAS探测器的数据建立整个分析，从事件选择和不确定性估计，到结果解释和利用，包括开发新技术来分离信号事件并减去不感兴趣的背景过程。

The key objectives of the research are to test Bell inequalities and other predictions of quantum information at unprecedented high energies in qubit (top-pair) and qutrit (Higgs boson) systems. Quantum information studies such as these have never been explored at hadron colliders before and have never been explored anywhere at these energies. Furthermore, the Higgs component of the project will involve isolating the H->WW->lepton + jets final state, an as-yet untested and unobserved Higgs decay mode. The student will set up the entire analysis using data from the ATLAS detector, from event selection and uncertainty estimation, through to result interpretation and exploitation, including developing novel techniques to isolate the signal events and subtract background processes that are not of interest.
