Welcome to the NeoPDF’s C++ APIs documentation!

NeoPDF is a fast, reliable, and scalable interpolation library for both collinear and transverse momentum dependent Parton Distribution Functions with modern features designed for both present and future hadron collider experiments.

• Beyond interpolations over the kinematic variables \((x, k_T, Q^2)\), NeoPDF also supports interpolations along the nucleon numbers \(A\) (relevant for nuclear PDFs and TMDs) and the strong coupling \(\alpha_s\).

• NeoPDF implements its own file format using binary serialization and LZ4 compression, prioritizing speed and efficiency over human-readable formats. A command Line Interface (CLI) is provided to easily inspect and perform various operations on NeoPDF grids.
