摘要:

我们目前的现象学结果$t\bar{t}j + X$生产在大型强子对撞机,设计即将到来的实验分析这一过程的兴趣。我们专注于那些情况下,$t\bar{t}j + X$过程被认为是一个信号。我们讨论目前的理论不确定性和相关输入参数的依赖进入计算。对于${\cal R}$分布,这取决于不变质量的$t\bar{t}j$系统,我们提出了参考的预测,在壳层上,$\overline{\mbox{MS}}$和MSR顶夸克质量重整化计划,后者计划应用到这个过程中的第一次。我们的结论是特别有趣的那些分析旨在提取顶夸克质量的横截面测量。

英文摘要:

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.
