POWHEG BOX和NLO之间的接口

An interface between the POWHEG BOX and MadGraph5_aMC@NLO

Paolo Nason, Carlo Oleari, Marco Rocco, Marco Zaro

摘要:

在本文中,我们提出了一个使用MadGraph5_aMC@NLO开发POWHEG BOX生成器的框架,用于计算矩阵元素。在此框架内,可以利用MadGraph5_aMC@NLO生成标准模型过程及其几个扩展的矩阵元素的所有灵活性,以及POWHEG BOX框架的所有功能,包括无需合并标度的多射流合并的可能性(使用所谓的MiNLO方法)。作为一个概念的证明,我们开发了一个发电机的生产自旋0希格斯玻色子与多达两个喷气机,CP违反耦合。

英文摘要:

In this paper we present a framework for developing POWHEG BOX generators using MadGraph5_aMC@NLO for the computation of the matrix elements. Within this framework, all the flexibility of MadGraph5_aMC@NLO for the generation of matrix elements for Standard Model processes and for several of its extensions can be exploited, as well as all features of the POWHEG BOX framework, including the possibility of multijet merging without a merging scale (using the so called MiNLO approach). As a proof of concept, we develop a generator for the production of a spin-0 Higgs-like boson in association with up to two jets, with CP-violating couplings.
