gepard 0.9.10

Tool for studying the 3D quark and gluon distributions in the nucleon

Synopsis

Gepard - tool for studying the 3D quark and gluon distributions in the nucleon

• Modelling Generalized Parton Distributions (GPD) and Compton form factors (CFF).
• Perturbative NLO QCD evolution of GPDs
• Calculation of deeply virtual Compton scattering (DVCS) and deeply virtual meson production (DVMP) observables to NLO accuracy.
• Fitting parametrized models to the experimental data.

Installation

Gepard is a Python package available from standard PyPI repository so you should be able to install the latest version together with the required dependencies by simply issuing

pip install gepard

Of course, you should have Python first (version 3.7 at the least), as well as pip, which all major Linux distributions have as standard package. See the documentation for alternative instalation from sources, which is also easy.

Gepard is developed on Linux, but is tested also on Windows and MacOS. Please complain if you have problems.

Using

See the documentation, available at https://gepard.phy.hr/. Also there are lots of examples in the tests subdirectory.

Citing

If you use Gepard for your scientific publications, you might want to cite the arXiv:hep-ph/0703179 paper where theoretical framework that is implemented in the Gepard code is described in some detail.
