摘要:

在这次演讲中,我们提出了第一个,数值稳定的,计算W,Z + 3喷截面在大型强子对撞机在QCD耦合的次领先的顺序所需的单圈振幅的结果。我们在BlackHat中实现了这些过程,BlackHat是一个基于on-shell方法的自动化程序。这些方法随着外部部分子数量的增加而扩展得非常好,并且适用于LHC中各种各样的唯象问题。

英文摘要:

In this talk, we present the first, numerically stable, results for the one-loop amplitudes needed for computing W,Z + 3 jet cross sections at the LHC to next-to-leading order in the QCD coupling. We implemented these processes in BlackHat, an automated program based on on-shell methods. These methods scale very well with increasing numbers of external partons, and are applicable to a wide variety of problems of phenomenological interest at the LHC.
