Outline of Final Research Achievements |
In quantum field theory describing phenomena of particle physics, there exists a parameter region called the "non-perturbative region", in which a valid method of analysis is still unknown. The analysis of this region is essential for understanding particle physics. In this work, we aim at resolving several problems of non-perturbative physics by using newly developed methods: We have shown the deep connection between the two different non-perturbative phenomena, "confinement" that contributes to the existence of nuclei and "chiral symmetry breaking" that contributes to the existence of mass, based on the lattice Z3-QCD model which is one of the modified models of quantum chromodynamics. We have also shown that the confining mechanism called "bion confinement" can play a significant role in particle physics, by investigating Adjoint QCD on compactified spacetime which is one of the modified versions of realistic particle physics theory.
