摘要:

本文提出了一个计算强子碰撞中顶夸克对产生总截面的程序。该计划考虑到最近的理论发展,如近似的次到次到主导阶微扰QCD校正,它允许通过单独的变化的因式分解和重整化尺度的理论不确定性的研究。此外,它提供了可能性,以获得作为运行顶夸克质量的函数的截面。该程序也可以应用到一个假设的第四夸克家庭提供的QCD耦合是标准的。

英文摘要:

We present a program to calculate the total cross section for top-quark pair production in hadronic collisions. The program takes into account recent theoretical developments such as approximate next-to-next-to-leading order perturbative QCD corrections and it allows for studies of the theoretical uncertainty by separate variations of the factorization and renormalization scales. In addition it offers the possibility to obtain the cross section as a function of the running top-quark mass. The program can also be applied to a hypothetical fourth quark family provided the QCD couplings are standard.
