AI中文摘要：
我们比较了标准NLO和$\ exttt{MiNLO}$方法在LHC上完整离壳$pp \ o t\ar{t}W^+ + X$过程的积分和微分截面水平上的表现。与NLO相反，在$\ exttt{MiNLO}$方法中（现在也可在HELAC-NLO框架中使用），重整化和因子化标度被动态提取，并包含了Sudakov形状因子。结果特别针对$pp \ o t\ar{t}W^+j$过程在微扰QCD的NLO精度下使用两种不同标度选择给出。还讨论了合并预测至两个喷注以改善完整离壳$pp \ o t\ar{t}W^+ + X$过程的整体建模。
英文摘要：
We compare the standard NLO and $\texttt{MiNLO}$ approaches for the full off-shell $pp \to t\bar{t}W^+ + X$ process at the LHC, at both the integrated and differential cross-section levels. Contrary to NLO, in the $\texttt{MiNLO}$ approach, which is now also available within the HELAC-NLO framework, renormalization and factorization scales are dynamically extracted and Sudakov form factors are incorporated. Results are particularly presented for the $pp \to t\bar{t}W^+j$ process at NLO accuracy in perturbative QCD using two different scale choices. Merged predictions up to two jets to improve the overall modeling of the full off-shell $pp \to t\bar{t}W^+ + X$ process are also discussed.
