Area of the work is Theoretical High Energy Physics. The more specific area of work is collider physics phenomenology [1]. The phenomenology in High Energy Physics require the computational technique. The main task is to calculate the scattering cross section for the particular scattering process. The cross section involves the phase space integration. The phase space integration is done using the Monte Carlo integration technique [2]. The FORTRAN and C++ program for Monte Carlo are available. The processes where the many particles in the final state will have the as many phase space integrations as the particles in the final states. Such processes will take time for computation.
At high energy processes the higher order corrections involves the tensor integration and gamma martices multipication. For many number of gamma matrices can be done by writing the program in FORM language [3].
Also the various researchers across the world are writing the packages to make the calculations easy. The current available packages are PYTHIA [4], MadGraph5 [5], HELAS [6], mc@nlo [7], FastJet [8], HERWEG [9]. MadGraph is the event generator [11]. Event generater calculate the matrix element. The calculation of matrix element and cross section involves the phase space calculation. These eevent generater use the monte carlo integration techniques to do integration. To run these packages need the high speed computers.
