论文摘要
我们报告了我们最近对各种理论方法的比较，以预测$ 3 \ ell $ decay频道的$ pp \ to t \ bar {t} w $的基准签名，$ \ mathcal {o}（α_s^3α^6）$和$ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ {o}（O}（O}（O}）（α_s）^8）$。比较包括固定阶预测，包括完全基于双回旋效应的预测以及通过采用狭窄的宽度标记来进行的预测。此外，我们使用MG5和Powheg-Box框架包括Parton-Shower匹配的预测。
We report on our recent comparison of various theoretical approaches to predict fiducial signatures for $pp\to t\bar{t}W$ in the $3\ell$ decay channel at $\mathcal{O}(α_s^3α^6)$ and $\mathcal{O}(α_sα^8)$. The comparison includes fixed-order predictions including full off-shell effects as well as predictions based only on the double-resonant contributions by employing the Narrow-Width-Approximation. Furthermore, we include parton-shower matched predictions using the MG5 and POWHEG-BOX frameworks.
