论文摘要
在本文中,我们提出了一个框架,用于使用MADGRAPH5_AMC@nlo开发POWHEG盒发电机来计算矩阵元素。在此框架内,可以利用MadGraph5_AMC@nlo的所有灵活性,用于为标准模型流程及其几个扩展程序生成矩阵元素,以及Powheg Box框架的所有功能,包括在不使用所谓的Minlo合并量表的情况下进行多喷式合并合并的所有功能。作为概念证明,我们开发了一种生产类似于Spin-0 Higgs的玻色子的生成器,最多具有两种喷气机,并带有CP侵入耦合。
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.
