摘要:

研究了在γ-γ对撞机上测量Higgs对产生的可行性。我们发现,最佳碰撞能量约为270 GeV,从灵敏度研究与希格斯玻色子玻色子的质量为120 GeV/c^2。在最佳碰撞能量下,主要背景是gamma gamma到WW、gamma gamma到ZZ和gamma gamma到bbbb。初步分析表明,HH可以观察到约5西格玛的统计意义,当我们选择正确的分配的轨道,通过使用颜色单态信息。

英文摘要:

We studied the feasibility of measurement of Higgs pair creation in a gamma gamma collider. We found the optimum collision energy is around 270 GeV from the sensitivity study with Higgs boson mass of 120 GeV/c^2. Main backgrounds are gamma gamma to WW, gamma gamma to ZZ, and gamma gamma to bbbb at the optimum collision energy. The preliminary analysis shows HH could be observed with the statistical significance of about 5 sigma when we chose correct assignment of a track by using color singlet information.
