用HELAC-NLO进行次领先的t级反t+喷流物理研究

Next-to-leading order t anti-t plus jets physics with HELAC-NLO

Malgorzata Worek

摘要:

本文报道了最近在CERN大型Hardon对撞机上对t anti-tb anti-b和t anti-t +2 j过程的次领先阶QCD计算。积分和微分截面的结果。在这两种情况下,观察到的尺度依赖性显着减少,这表明微扰膨胀得到很好的控制。结果是在HELAC-NLO系统的框架下得到的。

英文摘要:

A report on the recent next-to-leading order QCD calculations to t anti-t b anti-b and t anti-t + 2j processes at the CERN Large Hardon Collider is presented. Results for integrated and differential cross sections are given. A significant reduction of the scale dependence is observed in both cases, which indicates that the perturbative expansion is well under control. The results are obtained in the framework of the HELAC-NLO system.
