John M Campbell, Stefan Höche, Christian T Preuss

摘要:

单圈矩阵元的计算是大型强子对撞机高光度相精确计算的主要瓶颈之一。为了缓解这个问题,一个新的C++接口的MCFM部分子级蒙特卡罗介绍,让访问一个广泛的库的分析结果的单回路振幅。定时比较提出了一个大的标准模型过程。这些都是相关的高统计事件模拟的实验分析和精度固定顺序计算的背景下。

英文摘要:

The evaluation of one-loop matrix elements is one of the main bottlenecks in precision calculations for the high-luminosity phase of the Large Hadron Collider. To alleviate this problem, a new C++ interface to the MCFM parton-level Monte Carlo is introduced, giving access to an extensive library of analytic results for one-loop amplitudes. Timing comparisons are presented for a large set of Standard Model processes. These are relevant for high-statistics event simulation in the context of experimental analyses and precision fixed-order computations.
