5th Intensive Lecture by Quantum Gravity Gatherings
2023 October 18, 19, 20 @ RIKEN, Wako, Japan
This is the fifth event hosted by the Quantum Gravity Gatherings (QGG) Study Group at RIKEN iTHEMS. For this event, we have invited Professor Shun'ya Mizoguchi from KEK, Tsukuba, to deliver pedagogical lectures on the F-theory and its relation to particle physics. We aim for this event to provide insights to researchers in related fields.
Originally, heterotic string theory was a promising candidate for describing our world, as it naturally incorporated Grand Unified Theory (GUT) based on an exceptional gauge group. However, heterotic theory encounters challenges in moduli fixing. On the other hand, type II theory has an advantage in moduli fixing, but realizing GUT proves to be challenging. The F-theory describes the strongly coupled type IIB string theory, fully utilizing string dualities. This theory appears to realize both the moduli fixing and GUT. Consequently, F-theory plays a central role in string phenomenology. Shun'ya is a leading expert in these areas. We are fortunate to have the opportunity to learn numerous insights into string theory as well as particle physics.
This intensive lecture series is designed to be an interactive event. To facilitate this, the number of participants will be limited to approximately 30. The intensive talk will be given in a face-to-face blackboard style (in English, no online streaming) to encourage informal and lively Q&A discussions. The program will also include short talk sessions, where participants can present a 5-minute talk on a topic of their choice, including their research, reviews of specific works, or future study interests.
Registration
Registration Form- The registration deadline for all participants is 3rd October (Tue). However, if the number of registered participants exceeds the capacity of the event room, we may need to close registration prior to the specified deadline.
- Participants are strongly encouraged to give a short talk on any topic of their choice (self-introduction, research, review of some works, what they want to research in the future, etc.). This interactive session is designed to foster a lively and engaging environment, facilitating increased communication and knowledge exchange among all participants.
- We can partially support the expenses for junior participants. Note that:
- giving a short talk is mandatory for students who will attend a banquet or receive support.
- we have a limited number of accommodations available for participants residing in remote areas. Please note that the check-in date is fixed as October 17th and the check-out date is set for October 20th; unfortunately, these dates cannot be changed.

Title: Introduction to F-Theory
Abstract: F-theory is a framework of non-perturbative compactifications of type IIB string theory. It is non-perturbative in the sense that the string coupling varies with their position in the compactification space, in which strongly coupled and weakly coupled regions coexist and reside next to each other. Such a non-perturbative property can never be realized in the so-called "non-perturbative formulation of string theory" that does not have S-duality. Meanwhile, it is the key to realize a string GUT model and the inflation of the early universe in a single theoretical framework.
F-theory has often been misunderstood. For example, that it is a 12-dimensional theory, or that it is an esoteric theory that uses algebraic geometrical methods. While they are correct in a sense, the essence of F-theory is not there. In this lecture, while clearing up such misconceptions, I would like to explain the basic ideas and techniques from the very beginning to understand the essence of F-theory. The contents of the lecture will include:
