| Outline of Final Research Achievements |
The dynamics of the electroweak gauge symmetry breaking in the standard model of particle physics is unknown yet. Though it has been investigated within the framewark of the quantum field theory, the solution has not been found yet. There have been further effort in String Theory beyond the quantum field theory, but it is still in a mistery. In this research we try to understand the dynamics by considering a dynamical system of D-brane, as a binary star, in String Theory. Though the detailed investigations within the string world sheet theory, it should be concluded that there is no such a possibility. The dynamics of the electroweak gauge symmetry breaking is still in a mistery.
