LoopStructural is an opensource Python library for 3D geological modelling. It can:

• Model fault networks integrating fault kinematics and overprinting relationships;

• Model folds using structural elements (fold axis, fold axial surface) for multiple fold events;

• Use different implicit interpolation algorithms (Finite Difference, Piecewiese Linear, RBF);

• Export models to vtk, geoh5, omf, gocad, csv, obj formats;

• Visualise models in an interactive python environment.

The Son of Grid Engine is a community project to continue Sun's old gridengine project after Oracle shut down the site and stopped contributing code.

Implementation of calculation of the hadron jet cross sections in C++.

This package provides font data for mplhep.

SISCone is an algorithm for identifying jets in high-energy particle collisions.

The HepMC package is an object oriented C++ event record for High Energy Physics Monte Carlo generators and simulation.

APFEL++ is a C++ rewriting of the Fortran 77 code APFEL originally conceived to evolve collinear parton distribution functions (PDFs). However, APFEL++ is based on a completely new code design and guarantees a better performance along with a more optimal memory management. The new modular structure allows for better maintainability and easier extensibility. This makes APFEL++ suitable for a wide range of tasks: from the solution of the DGLAP evolution equations to the computation of deep-inelastic-scattering (DIS) and single-inclusive-annihilation cross sections. Also more complex computations, such as differential semi-inclusive DIS and Drell-Yan cross sections, are easily implementable in APFEL++.

ThePEG is a toolkit for implementing HEP event generators, used as the common event-generation framework underlying Herwig 7.

The Scikit-HEP project (HEP stands for High Energy Physics, see more in the FAQ) is a community-driven and community-oriented project with the aim of providing Particle Physics at large with an ecosystem for data analysis in Python.

CHAPLIN enables you to numerically evaluate Harmonic polylogarithms up to weight 4 for any complex argument.

This package provides a library of 3rd-party add-ons to FastJet.

This package provides a small and thin Python interface to read Les Houches Event (LHE) files.

HOPPET is a Fortran package for carrying out DGLAP evolution and other common manipulations of PDFs. It also includes C++ and Python interfaces to many of the key features.

The HepMC package is an object oriented C++ event record for High Energy Physics Monte Carlo generators and simulation.

This package provides a Pythonic Jupyter-friendly Python API for the HepMC3 library.

pyhepmc has been optimised for safety, usability, and efficiency by a human expert, something that an automatic tool cannot provide. It brings these unique features:

• Python idioms are supported where appropriate.

• Simple IO with pyhepmc.open.

• An alternative Numpy API whih accelerates event processing.

• The public API is fully documented with Python docstrings.

• Objects are inspectable in Jupyter notebooks.

• Events render as graphs in Jupyter notebooks.

CLHEP is a set of HEP-specific foundation and utility classes such as random generators, physics vectors, geometry and linear algebra. CLHEP is structured in a set of packages independent of any external package.

Rivet is a system for preservation of particle-collider analysis logic, analysis reinterpretation via MC simulations, and the validation and improvement of Monte Carlo event generator codes. It covers all aspects of collider physics, from unfolded precision measurements to reconstruction-level searches, and physics from the Standard Model to BSM theories, and from perturbative jet, boson and top-quarks to hadron decays, inclusive QCD, and Heavy Ion physics.

Sherpa is a Monte Carlo event generator for the Simulation of High-Energy Reactions of PArticles in lepton-lepton, lepton-photon, photon-photon, lepton-hadron and hadron-hadron collisions. Simulation programs - also dubbed event generators - like Sherpa are indispensable work horses for current particle physics phenomenology and are (at) the interface between theory and experiment.

LHAPDF is the standard tool for evaluating PDFs in high-energy physics. PDFs encode the flavour and momentum structure of composite particles, such as protons, pions and nuclei; most cross-section calculations are based on parton-level matrix-elements which must be connected to the real interacting particles, hence PDFs are an essential ingredient of phenomenological and experimental studies at hadron and heavy-ion colliders (e.g. LHC, HERA, Tevatron, EIC, FCC) and in cosmic-ray physics.

CLHEP is a set of HEP-specific foundation and utility classes such as random generators, physics vectors, geometry and linear algebra. CLHEP is structured in a set of packages independent of any external package.

This package provides example files (e.g. ROOT) for testing and developing HEP packages against.

The FastJet package provides a fast implementation of several longitudinally invariant sequential recombination jet algorithms, in particular the longitudinally invariant k_t jet algorithm, the inclusive longitudinally invariant version of the Cambridge/Aachen jet-algorithm, and the inclusive anti-k_t algorithm.
