论文摘要
SMEFTSIM软件包旨在在标准模型有效场理论（SMEFT）中启用自动化计算，其中Sm Lagrangian的范围是六个操作员的完整基础。它包含一组用feynrules编写的模型，并预先出口到UFO格式，以在Monte Carlo事件发生器中使用。这些模型的风味假设以及为电动扇形选择的输入参数有所不同。本文档提供了一个独立的教学参考，该参考可以收集与SMEFTSIM使用相关的所有理论和技术方面，并记录了版本3.0版本的发布。与先前的发行版相比，通过SM中的Gluon融合对HIGGS产生的描述得到了显着改善，已经添加了顶级夸克部门研究的两个风味假设，并实施了一项新功能，可以将线性化的SMEFT校正处理给不稳定颗粒的传播器。
The SMEFTsim package is designed to enable automated computations in the Standard Model Effective Field Theory (SMEFT), where the SM Lagrangian is extended with a complete basis of dimension six operators. It contains a set of models written in FeynRules and pre-exported to the UFO format, for usage within Monte Carlo event generators. The models differ in the flavor assumptions and in the input parameters chosen for the electroweak sector. The present document provides a self-contained, pedagogical reference that collects all the theoretical and technical aspects relevant to the use of SMEFTsim and it documents the release of version 3.0. Compared to the previous release, the description of Higgs production via gluon-fusion in the SM has been significantly improved, two flavor assumptions for studies in the top quark sector have been added, and a new feature has been implemented, that allows the treatment of linearized SMEFT corrections to the propagators of unstable particles.
