我们为局部算子的威尔逊系数数值定义了一种数据交换格式,参数化了标准模型之外的物理低能效应。该格式有助于连接特定于模型的威尔逊系数计算器、重正化群 (RG) 运行程序和可观测计算器。它的设计是明确的(定义一组非冗余的运算符,在每个基础上具有固定的标准化)、可扩展(允许用户添加新的 EFT 或基础)和稳健(基于行业标准文件格式,并具有以多种编程语言实现的解析器)。我们已经实现了标准模型 EFT (SMEFT) 和弱电尺度以下的弱有效理论 (WET) 的格式,并为许多处理 SMEFT 或 WET 的公共代码添加了接口。我们还提供命令行实用程序和 Python 模块,以便方便地操作 WCxf 文件,包括不同库之间的转换以及从 SMEFT 到 WET 的匹配。 (C) 2018 Elsevier B.V. 保留所有权利。
We define a data exchange format for numerical values of Wilson coefficients of local operators parameterising low-energy effects of physics beyond the Standard Model. The format facilitates interfacing model-specific Wilson coefficient calculators, renormalisation group (RG) runners, and observable calculators. It is designed to be unambiguous (defining a non-redundant set of operators with fixed normalisation in each basis), extensible (allowing the addition of new EFTs or bases by the user), and robust (being based on industry standard file formats with parsers implemented in many programming languages). We have implemented the format for the Standard Model EFT (SMEFT) and for the weak effective theory (WET) below the electroweak scale and have added interfaces to a number of public codes dealing with SMEFT or WET. We also provide command-line utilities and a Python module for convenient manipulation of WCxf files, including translation between different bases and matching from SMEFT to WET.
