- AcerMC Monte Carlo Generator - The AcerMC Monte-Carlo event generator is dedicated for generation of the Standard Model background processes in pp collisions at the LHC.
- CalcHEP - Software for model building and collider phenomenology.
- cfortran.h - Interfacing C/C++ and FORTRAN - cfortran.h is a single header file that allows you to easily use fortran code in c and c++. Very useful for using HBOOK and other CERNLIB code in new c++ applications.
- CompHEP - Package for evaluation of Feynman diagrams, integration over multi-particle phase space and event generation.
- Elementary Particles Simulation - Elementary Particles Simulation using Java Technology.An application made for educational purposes.
- FeynArts - Mathematica package for generation and visualization of Feynman diagrams and amplitudes.
- FeynCalc - Mathematica package for algebraic calculations in elementary particle physics, focusing on Feynman diagram calculations.

- FLUKA (Fluktuierende Kaskade) - A stand-alone particle physics Monte-Carlo simulation package. It is being used as a simulation tool in a number of experiments.
- FreeHEP - Virtual organization involved in the development of open-source software for data analysis and visualization, primarily for use in high energy, nuclear and astro- physics.
- Hanna - A C-based Analysis Tool for the HERMES experiment at the DESY laboratory in Hamburg, Germany.
- HERWIG - A Monte Carlo package for simulating hadron emission reactions with interfering gluons. Also includes a list of some "competitor" generators.
- Monte Carlo Number Scheme - MC particle numbering convention, endorsed by the Particle Data Group.
- Pandora - A physics event generator for linear collider studies. It includes beamstrahlung, initial state radiation, hadronization, and full treatment of polarization effects.
- Povama - Persint OpenGL Visualization for ATLAS Muon Analysis. Software used to visualize the reconstruction of muon traces.
- PYTHIA (and JETSET) - An event generator for a large number of physics processes. The site contains the latest source, the official manual and a short write-up describing PYTHIA's status with respect to the physics.
- StdHep - Provides a common output format for Monte Carlo events so that event generators and other simulators can easily be compared. It also provides a set of routines which convert Herwig, Jetset, Isajet, or QQ events to and from the standard HEP event format.
- Texsis - TeX Macros for Physicists - This package provides a number of useful features for typesetting research papers. It is an extension to Plain Tex.
- The ROOT System - An object oriented framework for large scale data analysis. ROOT is a C++ replacement of the popular PAW program developed at CERN.
