论文摘要
我们介绍了$ t \ bar {t} J + x $生产的现象学结果，该结果是设计该过程即将进行的实验分析的感兴趣的。我们专注于$ t \ bar {t} j + x $进程被视为信号的情况。我们讨论了理论不确定性以及对输入参数的依赖，进入计算。对于$ {\ cal r} $分布，这取决于$ t \ bar {t} j $ - 系统的不变质量，我们在壳中介绍参考预测，$ \ overline {\ mbox {ms}}} $和msr Top-Quark top-Quark Quark质量renulatization Schemes，应用于该过程，以适用于该过程中的第一个时间。对于那些旨在从横截面测量值中提取顶级质量质量的分析，我们的结论特别有趣。
We present phenomenological results for $t\bar{t}j + X$ production at the Large Hadron Collider, of interest for designing forthcoming experimental analyses of this process. We focus on those cases where the $t\bar{t}j + X$ process is considered as a signal. We discuss present theoretical uncertainties and the dependence on relevant input parameters entering the computation. For the ${\cal R}$ distribution, which depends on the invariant mass of the $t\bar{t}j$-system, we present reference predictions in the on-shell, $\overline{\mbox{MS}}$ and MSR top-quark mass renormalization schemes, applying the latter scheme to this process for the first time. Our conclusions are particularly interesting for those analyses aiming at extracting the top-quark mass from cross-section measurements.
