Research Abstract

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.
