我们提出了第一个完全自动化的实现循环引起的过程的横截面计算和事件生成。这项工作已纳入M ad G 5_ a MC@ NLO框架。我们描述了在矩阵元素评估，相空间集成和事件生成的水平上实现的优化，允许模拟大的多重性循环引起的过程。沿着一些选定的微分观测量，我们用一个表格来说明我们的结果，该表格显示了SM中最多三个终态的所有环诱导强子散射过程以及一些相关的2→ 4过程的包含截面。其中许多是第一次计算。
We present the first fully automated implementation of cross-section computation and event generation for loop-induced processes. This work is integrated in the M ad G raph 5_ a MC@ NLO framework. We describe the optimisations implemented at the level of the matrix element evaluation, phase space integration and event generation allowing for the simulation of large multiplicity loop-induced processes. Along with some selected differential observables, we illustrate our results with a table showing inclusive cross-sections for all loop-induced hadronic scattering processes with up to three final states in the SM as well as for some relevant 2→ 4 processes. Many of these are computed here for the first time.
