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, kT, Q2), NeoPDF also supports interpolations along the nucleon numbers A (relevant for nuclear PDFs and TMDs) and the strong coupling αs.
-
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.
