GUMP: Generalized Parton Distributions through Universal Moment Parameterization

This repository contains the source code for the Generalized Parton Distributions through Universal Moment Parameterization (GUMP) program, designed for global analysis of GPDs.

Overview

• GPD Calculations:
  The script under folder /Examples provides example workflows to generate PDFs, GPDs and cross-sections using GUMP parameters obtained from the fitting program.

• Performance Note:
  Evaluating GPDs can be computationally intensive, as it involves QCD evolution in moment space and numerical contour integrals to transform back to the momentum fraction (x) space.

Usage

• For simple usage install through pip by pip install gumpgpd. Check the script under /Examples for example usage.

• For modified package and developer download the whole branch and run pip install -e . to install locally (Make sure to pip uninstall gumpgpd to avoid conflicts if you install the pip version already)

Change log

• ** v.1.0.1 **: bug fix in GPD calculations.
