标准模型$H γγ$与ATLAS的发现潜力

Standard Model $H γγ$ discovery potential with ATLAS

Yaquan Fang

摘要:

本文总结了利用ATLAS探测器进行$H γγ$衰变的标准模型希格斯玻色子的发现潜力。光子重建,光子识别和触发问题的相关探测器性能方面进行了讨论。研究了包含$H γγ$和希格斯玻色子搜索与一个或两个硬喷流的潜力。最后使用未分组的多变量最大似然拟合与预期的积分亮度光度$\approx 10 fb^{-1}$来评估发现潜力。

英文摘要:

This contribution summarizes the discovery potential of the Standard Model Higgs boson using the $H γγ$ decay with the ATLAS detector. The relevant detector performance aspects of photon reconstruction, photon identification and trigger issues are discussed. The potential of inclusive $H γγ$ as well as Higgs boson searches in association with one or two hard jets are studied. The discovery potential is finally assessed using an unbinned multivariate maximum-likelihood fit with an expected integrated luminosity of $\approx 10 fb^{-1}$.
