Search for New Physics through the Measurement of Yukawa coupling of b-quark and Development of Silicon Detector

我们安装和维护了带电粒子跟踪器，并针对希格斯搜索详细检查了b夸克的识别方法。这导致了寻找希格斯衰变到b夸克对的事件的准备工作。在采集数据的同时，我们还测量了希格斯搜索中最重要的背景源之一的ttbar事件的截面。此外，我们还研制了新型硅探测器，并验证了探测原理。

We installed and maintained the charged particle tracker and examined the b-quark identification method in detail, aiming for the Higgs search. This results in the preparation of the search for events where Higgs decays to b-quark pair. While we take data, we also measured the cross section of ttbar event which is one of the most important background sources in the Higgs search. Besides, we developed new type of silicon detector, and confirmed the proof of detection principle.
