论文摘要
拟合PDF需要将广泛的数据集集成到从数据和理论方面的各种数据集中。对于数据，集成主要由数据格式的标准化组成，但对于理论预测，涉及多种成分。不同的提供商是由单独的组开发的，用于不同的过程，具有多种输入（Runcard）和输出（插值网格）。此外，由于在不同的尺度上测量过程，因此必须为PDF候选者提供DGLAP演化，或者预先计算到网格中。我们正在努力在独特的框架中朝着所有这些步骤的自动化，这对于任何PDF拟合组都有用，也可能对现象学研究有用。
Fitting PDFs requires the integration of a broad range of datasets, both from data and theory side, into a unique framework. While for data the integration mainly consists in the standardization of the data format, for the theory predictions there are multiple ingredients involved. Different providers are developed by separate groups for different processes, with a variety of inputs (runcards) and outputs (interpolation grids). Moreover, since processes are measured at different scales, DGLAP evolution has to be provided for the PDF candidate, or precomputed into the grids. We are working towards the automation of all these steps in a unique framework, that will be useful for any PDF fitting groups, and possibly also for phenomenological studies.
