About PDFxTMDLib

PDFxTMDLib provides a common, extensible framework for collinear parton distribution functions and transverse-momentum-dependent distributions in C++ and Python.

The project is designed for high-energy-physics calculations that need efficient grid evaluation while retaining control over file reading, interpolation, extrapolation, uncertainty analysis, and strong-coupling evaluation. The project paper describes the architecture and presents validation comparisons with established PDF and TMD tools.
