论文摘要
鉴于3L通道中该过程TTW的理论与实验之间的最新张力，我们提出了精心选择的可观察物的现象学研究。我们在NLO QCD上对TTW+和TTW-使用完整的外壳结果来构建横截面比率，可观察到的可观察到的扰动稳定性有望增强。此外，我们还在基准综合水平上重新审视顶部的电荷不对称及其衰减产物。对于所有可观察到的，研究了建模的影响。
In light of recent tension between theory and experiment for the process ttW in the 3l channel, we present a phenomenological study of carefully chosen observables. We employ the full off-shell results at NLO QCD for ttW+ and ttW- to build the cross section ratio, an observable which is expected to exhibit enhanced perturbative stability. Furthermore, we also revisit the charge asymmetries of the top and its decay products at the fiducial integrated level. The impact of modelling is investigated for all observables.
