Mathematica package for generation and visualization of Feynman diagrams and amplitudes.

MC particle numbering convention, endorsed by the Particle Data Group.

Two Tools designed to calculate cross sections in high energy physics.

Extension of the Mathematica packages, FeynCalc and FeynArts.

Mathematica package for algebraic calculations in elementary particle physics, focusing on Feynman diagram calculations.

An object oriented framework for large scale data analysis. ROOT is a C++ replacement of the popular PAW program developed at CERN.

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.

This package provides a number of useful features for typesetting research papers. It is an extension to Plain Tex.

A stand-alone particle physics Monte-Carlo simulation package. It is being used as a simulation tool in a number of experiments.

Provides CERNLIB documentation. Also provides tutorials, FAQs, newsletters and reference cards for a wide range of software.

The Fermilab Software Tools Program (Fermitools) aims to provide useful tools to the community. A wide range of tools are available, and all are free.

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.

A physics event generator for linear collider studies. It includes beamstrahlung, initial state radiation, hadronization, and full treatment of polarization effects.

A Monte Carlo package for simulating hadron emission reactions with interfering gluons. Also includes a list of some "competitor" generators.

Free C++ library for drawing Feynman diagrams. The output is in PostScript, which can be used in TeX or printed directly.

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.

Persint OpenGL Visualization for ATLAS Muon Analysis. Software used to visualize the reconstruction of muon traces.

The AcerMC Monte-Carlo event generator is dedicated for generation of the Standard Model background processes in pp collisions at the LHC.
