Automatic calculation of particle interaction or decay is part of the Computational Particle Physics branch. It refers to methods and computing tools to help computing the complex particle interaction or decay occurring in high energy physics, astroparticle detection and cosmology research. Particle Accelerator and colliders generate interaction of "elementary" particle (like electron and protons) named 'Initial State' producing particles in the 'Final State'. For example at LEP, is a process where the 'initial state' is an electron and a positron colliding to produce an electron and a positron, the 'final state'. In this simple case, no automatic packages are needed and in the simplest case analytical formulae can be easly derived. But particle physics is now facing much more complex calculation like at LHC where 'p' are protons and 'n jets' means n (2,3,...) jets of particles initiated by protons constituents (quarks and gluons. The number of subprocesses for a given initial state and final state is so large that automatic tools have been developed to mitigate the burden of hand calculations.
