论文摘要
目前，在大型强子对撞机（LHC）中使用的HADRONIC Z衰变的仿真忽略了Hadroonic Z Boson的Electroweak生产与量子染色体动力学（QCD）生产的效果。实际上，Diboson Monte Carlo样品是独立于QCD过程产生的。该项目的目的是通过研究这些干扰效应来评估这种模拟方法的有效性，并将蒙特卡洛样品与实验数据进行比较。特别是，首次探索了低横向动量的区域，揭示了这些地区独有的新挑战。第一次在低横向动作机上找到了ZZ $ \ rightarrow $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ b \ bar {b}μ\barμ$的三个sigma证据。但是，质量峰值的误差太大，无法提供任何有足够的干扰证据。因此，没有证据表明LHC采用的模拟策略不足。
At present, the simulations for hadronic Z decay used at the Large Hadron Collider (LHC) neglect the effects of interference between the electroweak production of the hadronic Z boson and the Quantum Chromodynamics (QCD) production of $q\bar{q}$. Indeed, the diboson Monte Carlo samples are generated independently from QCD processes. The purpose of this project is to assess the validity of this simulation approach by studying these interference effects, comparing Monte Carlo samples to experimental data. In particular, regions of low transverse momenta are explored for the first time, revealing new challenges unique to these regions. Three sigma evidence for ZZ $\rightarrow$ $b\bar{b}μ\barμ$ is found at low transverse momenta for the very first time. However, the error on the mass peak is too large to provide any sufficient evidence for interference. As such, there is no evidence to suggest that the simulation strategies adopted at the LHC are inadequate.
