Search for Higgs Particle in high energy proton collision experiment

在LHC加速器和ATLAS探测器上，我们获得了质心能量分别为900GeV、2、36TeV和7TeV的第一次碰撞数据。电子和光子是本研究中寻找希格斯粒子的主要探测器。我们研究了电子和光子的重建和识别，并在一次国际会议上报告了结果。在这项研究中，内部探测器起着关键作用。我们成功地获取了高质量的数据，这一点在日本物理学会会议上得到了报道。作为背景研究，研制了一台用于QCD中双光子产生的高阶修正事件发生器。结果在日本物理学会会议上发表了报告。

In LHC accelerator and ATLAS detector, we obtained the first collision data at the center of mass energy of 900 GeV, 2, 36 TeV and 7 TeV. Electrons and photons are main probe to search for Higgs particle in this study. We studied reconstruction and identification of electrons and photons and report the results in an international conference. The inner detector plays a key role in this study. We successfully took high quality data, which was reported in Japanese Physical Society Meeting. As a study of background, an event generator for di-photon production in QCD with higher order correction was developed. The result was report in Japanese Physical Society Meeting.
