Workshop on Very Light Dark Matter 2021

Date: September 27-29, 2021

Venue: Online (Zoom)

The present universe is filled with dark matter. Although it is still unclear what dark matter is made of, it is known to have played an extremely important role in the formation of the structure of the universe such as galaxies and galaxy clusters. Recently, dark matter with extremely low mass has attracted much attention. In this workshop, recent experimental results as well as future prospects, and theoretical progress of very light dark matter will be discussed. We will have invited talks by experts in the related fields, as well as contributed talks. One of the aims of this workshop is to deepen the understanding of recent developments and future prospects in this field through discussions among the participants. The following is a list of representative topics.

  • Axion and axion like particles
  • Dark photon and other light dark matter
  • Light dark matter search experiments
  • Black hole superradiance
  • Cosmic birefringence
  • Structure formation
  • Weak gravity conjecture
