论文摘要

搜索独家的Hadronic矢量玻色子衰变是LHC计划的持续部分,迄今为止,尚未观察到这种衰减。除了对分支比率的内在兴趣外,还可以测量$ w $玻色子质量,与通常的方法完全不同。辐射衰减模式为这次搜索提供了良好的潜在渠道;但是,我们重点介绍了以前没有讨论过的三个问题:粒子错误识别,部分重建和干扰QCD的影响。这些问题导致数十个或数百个MEV/c $^2 $的峰位置变化。

The search for exclusive hadronic vector boson decays is an ongoing part of the LHC programme where, to date, no such decays have been observed. In addition to the intrinsic interest in the branching ratios, there is potential for a measurement of the $W$ boson mass quite distinct from the usual methods. The radiative decay modes offer good potential channels for this search; however, we highlight three issues with it not previously discussed: particle misidentification, partial reconstruction and the impact of interference with QCD. These issues cause shifts in the peak position of tens or hundreds of MeV/c$^2$.
