论文摘要
这项研究展示了Lepton识别的方法和$γγ$缓解质量中心能量$ \ sqrt {s} = 500 $ GEV的半蛋白质WW衰减在ILC上。使用具有ILD探测器概念的完全模拟的标准模型蒙特卡洛事件进行分析，并强调W质量的测量。质量测量是通过鉴定Lepton和将其余系统作为HADRONIC W-BOSON进行的。仅考虑WW生产的最有利的光束极化场景。获得的探测器性能基准获得了$ 1600 $ fb $^{ - 1} $的集成亮度，这是W质量的统计错误，$Δm_{w} $（stat。）$ = 2.4 $ meV，ww crosssection of $δσ/σ$ = 0.0036 $ = 0.036 c。
This study showcases the approaches towards lepton identification and $γγ$ mitigation at center-of-mass energy $\sqrt{s} = 500$ GeV for semileptonic WW decays at the ILC. The analysis is performed using fully simulated Standard Model Monte Carlo events with the ILD detector concept and emphasizes the measurement of the W mass. The mass measurement is performed through the identification of a lepton and treatment of the remaining system as the hadronic W-boson. Only the most favorable beam polarization scenario for WW production is considered. The resulting detector performance benchmark obtained, with an integrated luminosity of $1600$ fb$^{-1}$ , is a statistical error on the W mass of $ΔM_{W}$ (stat.)$ = 2.4$ MeV and a relative statistical error on the WW crosssection of $Δσ/σ$(stat.)$ = 0.036\%$.
