KEK Theory Workshop is an annual workshop on string theory and quantum field theory. Since KEK Theory Workshop 2014, it has been held as an international workshop. Speakers are invited from abroad as well as from Japan, and all talks are given in English.

We hope the workshop provides a valuable opportunity to have active discussions and inspiration on various fundamental problems in theoretical physics related to superstrings, supersymmetric gauge theories, black hole physics, quantum field theories, condensed matter physics, and so on.

This year, in the light of COVID-19, we have decided to hold the workshop ONLINE from Dec. 7 (Tue.) to Dec. 9 (Thu.) in JST (UTC+9). This year, we plan to have a variety of talks on string theory looking ahead to the post-LHC era.

The tentative list of invited speakers is:

  • Lara Anderson (Virginia Tech.)
  • Ignatios Antoniadis (LPTHE)
  • Jonathan Esole (Northeastern U.)
  • Hiroshi Itoyama (Osaka City U.)
  • Tatsuo Kobayashi (Hokkaido U.)
  • Susha Parameswaran (U. of Liverpool)
  • Stuart Raby (Ohio State U.)

We will also have short talks with (15+5) minutes. Participants can apply for the talk at the registration. The topics to be discussed in the short talks can be chosen from field theory and string theory, and need not be related to the topic of invited talks. If there are too many applicants, we will have to make some selection. Some of the talks may be given in parallel sessions. 


Registration deadline

Those who wish to apply for a short talk: Nov. 7 (Sun.)
Other participants: Nov. 30 (Tue.)

The registration will be closed when the number of the applicants exceeds 300, which is the capacity of our Zoom meeting room.

NOTE: We will use the virtual meeting rooms on Zoom. The necessary information (links, IDs, and passcodes) will be sent to the participants by E-mail before the workshop starts.


We are looking forward to your participation.
