Outline of Final Research Achievements

In particle physics, quantum field theory is a framework for describing the particle and field. The perturbative approach to quantum field theory is indispensable for the analysis of high energy particle experiments, such as LHC, ILC and KEKB. By the discovery of Higgs boson like particle, the deviation from the Standard Model is quite important to find the phenomenon beyond the standard model and a new particle. The calculations of higher order corrections are enormous, so that a system for automation is necessary. We developed theoretical formulation and system for the automation of 2 loop calculations.
