Topics Covered

There have been annual workshops in Kyoto on string theory and quantum field theory for more than 20 years. Each year, around 150 participants gathered and there are around 40 short talks and 5 invited talks as well as poster sessions. This annual workshop is definitely one of the largest workshops of this field in Japan. The contents of the past conferences are archived here. Various topics discussed in the past workshops include:

This year we invite a few speakers from abroad and all the talks will be in English.


The registration site is here. The registration information can be changed here.

There is no registration fee.

The deadline of the registration for giving talks is Friday, October 9th.
The deadline of the registration for participation is Friday, November 6th.

The workshop consists of oral sessions and poster sessions. At the registration, a 20-minute plenary talk or a presentation at virtual poster sessions can be chosen. We will try to accommodate your preference, but we may need to limit the number of talks. The abstract submitted at the registration will be announced at the web site later.

Slides in oral sessions and files in poster sessions will be uploaded at this web site and submitted to the online Japanese journal "Soryushiron Kenkyu" (translated as "Research in high-energy physics"). We will not separately publish proceedings for this workshop. Please contact the organizers if you do not want to disclose your slides or poster files. All the talks will be broadcast online.


This year's workshop is conducted online, and therefore we do not support travel expenses.
