Standard Model from superstring theory

Superstring theory is a prime candidate for a theory that can explain all four forces of nature. However, it fails to explain why spacetime is three-dimensional. The IKKT matrix model was proposed as a model, strongly connected to superstring theory, which can answer such a fundamental question, supported by much evidence over the years. For the IKKT matrix model to truly be a complete theory of everything, it should also be able to explain why an “exact” set of particles in the Standard Model is necessary to describe three forces, except gravity. Despite many attempts, this still remains an open question. In this research, we transformed the IKKT matrix model to a more field theoretic picture, which resulted in a simpler and more straightforward investigation. With our setup, we found 4 generations of quarks and leptons. Despite a slight difference from the 3 generations in the Standard Model, this marks an important milestone in the research of the IKKT matrix model as a complete theory of everything. We are currently exploring other possible setup that results in a consistency with the Standard Model.

‍派遣中に学んだことや得られたもの

During my PhD studies, my research mainly focuses on investigating physical systems using numerical methods. During my visit to NTU, I had an opportunity to explore a new direction of research, including advanced usage of group theory in string compactification, which I have had little experience in. Therefore, the Dispatch Program has given me an opportunity to expand my research repertoire which is beneficial for my future career.
