轻夸克的顶部:QCD中两圈的完全质量依赖

Tops from Light Quarks: Full Mass Dependence at Two-Loops in QCD

M. Czakon

摘要:

提出了在无质量夸克-反夸克湮灭通道中产生有质量夸克-反夸克对的双圈QCD修正。结果是作为高能量极限附近质量的深度膨胀和微分方程系统的数值积分的组合而获得的。主要应用的结果和开发的方法是顶夸克对生产在大型强子对撞机。

英文摘要:

I present the two-loop QCD corrections to the production of a massive quark-anti-quark pair in the massless quark-anti-quark annihilation channel. The result is obtained as a combination of a deep expansion in the mass around the high energy limit and of a numerical integration of a system of differential equations. The primary application of the outcome and developed methods is top quark pair production at the Large Hadron Collider.
