摘要:

本文介绍了在大型强子对撞机(LHC)上通过矢量玻色子聚变机制与中心光子相结合发现标准模型希格斯玻色子玻色子衰变为$b\bar{b}$对的前景。尽管横截面减小了大约$α_{em}$的因子,光子提供了干净的触发和若干优点。在应用各种优化的选择标准后,我们使用ALPGEN与PYTHIA接口获得了$\sim$ 1.9的显著性。考虑了预期的$b$ -喷流效率和假率以及其他探测器接受度,以获得更真实的结果。

英文摘要:

We present the prospects for the discovery of a Standard Model Higgs boson decaying to $b\bar{b}$ pair through the Vector Boson Fusion mechanism in association with a central photon at the Large Hadron Collider (LHC). The photon provides a clean trigger and several advantages despite the fact that the cross section decreases by approximately a factor of $α_{em}$. After applying various optimized selection criteria, we obtain a significance of $\sim$1.9 using ALPGEN interfaced with PYTHIA. The expected $b$-jet efficiency and fake rates and other detector acceptance cuts are taken into account to obtain a more realistic result.
